The editor-viewer is tabbed, configure it on the Konfigurator General page Viewer To view a file as fast as possible according to its type, just put it under the cursor and press F3. &krusader;'s internal viewer is actually a part of &konqueror;, which can basically view every file type viewable by &konqueror; (⪚ display pictures, play music, show the content of an archive). This is called the 'Generic viewer', for which you need to configure the MIME types. The viewer works as follows: It tries to view the file with the 'Generic viewer'. When the file type (MIME type) cannot be determined or when a file (⪚ a binary) does not have an associated action, it disables the 'generic viewer'. The file is treated as a text file, which is the 'Text viewer'. The user can change in the KrViewer menu between: 'Generic viewer' (if available), 'Text viewer' and 'Hex viewer'. You can configure the default viewer mode on the Konfigurator General page . &Shift; F3 views a &URL; on demand, ⪚: man:/ views the manpages. man:/krusader views manpage of &krusader;. info:/ views the infopages. http://krusader.sourceforce.net/ views a webpage. ftp://ftp.kde.org/pub/kde/ views a &FTP; server. sftp://sftp.foo/ views a secure &FTP; server. file:/home/frank views the home directory of Frank. tar:/home/frank/archive.tar.gz/ opens content browser window for the tar.gz archive. KrViewer can have the following menus: File, Edit, View, Settings and Krviewer, depending on which file type is viewed. They will be discussed in the Editor section. The internal viewer can follow links on &HTML; pages. With &Ctrl;&Shift; E the viewer can start &krusader;'s internal editor (which is basically the same application). The embedded viewer is not written by us, it is supplied via &kf5; and KIO Slaves. We cannot and do not want to change it, using these libraries reduces the amount of written code. So we do not have to reinvent the wheel ;-) Editor Editor &krusader;'s internal editor has almost everything that you can expect of an editor. Editing is similar to viewing but with the F4 key. The default editor is &krusader;'s internal editor. You can change the default editor in the Konfigurator General page, if you prefer to use an external editor. When you use &krusader;'s internal editor for the first time, it is recommended to look at each section of the Settings menu, and configure it the way you want it. Menu overview There are different menus and menu items in simple and advanced mode. The advanced mode is enabled by checking the option Enable power user mode (&kde; 3 mode) on the Appearance page in &kappname;s settings. The File Menu &Ctrl;S File Save This saves the current document. If there has already been a save of the document then this will overwrite the previously saved file without asking for the user's consent. If it is the first save of a new document the save as dialog (described below) will be invoked. File Save As... This allows a document to be saved with a new file name. F5 File Reload Reloads the active file from disk. This command is useful if another program or process has changed the file while you have it open in &kappname;. &Ctrl;P File Print... Opens a simple print dialog allowing the user to specify what, where, and how to print. File Export as HTML Export your file in &HTML; format so your document can be viewed as a web page. This item is only displayed when the plugin Exporter is loaded. The Edit Menu &Ctrl;Z Edit Undo This is used to eliminate or reverse the most recent user action or operation. &Ctrl;&Shift;Z EditRedo This will reverse the most recent change (if any) made using Undo &Ctrl;X EditCut This command deletes the current selection and places it on the clipboard. The clipboard is a feature that works invisibly to provide a way to transfer data between applications. &Ctrl;C EditCopy This copies the currently selected text to the clipboard so that it may be pasted elsewhere. The clipboard is a feature that works invisibly to provide a way to transfer data between applications. &Ctrl;V EditPaste This will insert the contents of the clipboard at the cursor position. The clipboard is feature that works invisibly to provide a way to transfer data between applications. EditCopy as HTML This copies the currently selected text to the clipboard as &HTML;. This item is only displayed when the plugin Exporter is loaded. &Ctrl;A EditSelect All This will select the entire document. This could be very useful for copying the entire file to another application. &Ctrl;&Shift;A EditDeselect Deselects the selected text in the editor if any. - + &Ctrl;&Shift;B EditBlock -Selection Mode (Power user mode) +Selection Mode Toggles Selection Mode. When the Selection Mode is BLOCK, you can make vertical selections, ⪚ select column 5 to 10 in lines 9 to 15. The status bar shows the current state of the Selection Mode, either BLOCK or LINE. - + Meta&Ctrl;V EditVI input -Mode (Power user mode) +Mode Switch to a vi-like, modal editing mode. This mode supports the most used commands and motions from vim's normal and visual mode and has an optional vi mode statusbar. This status bar shows commands while they are being entered, output from commands and the current mode.The behavior of this mode can be configured in the Vi Input Mode section of the Editing page in &kappname;'s settings dialog. Ins EditOverwrite Mode Toggles the Insert/Overwrite modes. When the mode is INS, you insert characters where the cursor is. When the mode is OVR, writing characters will replace the current characters if your cursor is positioned before any character. The status bar shows the current state of the Overwrite Mode, either INS or OVR. &Ctrl;F EditFind... This opens the incremental search bar at the bottom of the editor window. On the left side of the bar is a button with an icon to close the bar, followed by a small text box for entering the search pattern. When you start entering characters of your search pattern, the search starts immediately. If there is a match in the text this is highlighted and the background color of the entry field changes to light green. If the search pattern does not match any string in the text, this is indicated by a light red background color of the entry field and Not found is displayed at the right side of the bar. Use the Next or Previous button to jump to the next or previous match in the document. You can choose whether the search should be case sensitive. Selecting Match Case will limit finds to entries that match the case (upper or lower) of each of the characters in the search pattern. Click on the button with a green arrow icon at the right side of the incremental search bar to switch to the power search and replace bar. F3 EditFind Next This repeats the last find operation, if any, without calling the incremental search bar. &Shift;F3 Edit Find Previous This repeats the last find operation, if any, without calling the incremental search bar, and searching backwards instead of forwards through the document. &Ctrl;R EditReplace... This command opens the power search and replace bar. On the upper left side of the bar is a button with an icon to close the bar, followed by a small text box for entering the search pattern. You can control the search mode by selecting Plain text, Whole words, Escape sequences or Regular expression from the drop down box. If Escape sequences or Regular expression are selected, the Add... menuitem at the bottom of the context menu of the text boxes will be enabled and allows you to add escape sequences or regular expression items to the search or replace pattern from predefined lists. Use the Next or Previous button to jump to the next or previous match in the document. Enter the text to replace with in the text box labeled Replace and click the Replace button to replace only the highlighted text or the Replace All button to replace the search text in the whole document. You can modify the search and replace behavior by selecting different options at the bottom of the bar. Selecting Match Case will limit finds to entries that match the case (upper or lower) of each of the characters in the search pattern. Selection Only will search and replace within the current selection only. The Find All button highlights all matches in the document and shows the number of found matches in a small popup. Click on the button with a green arrow icon at the right side of the power search and replace bar to switch to the incremental search bar. &Ctrl;H EditFind Selected Finds next occurrence of selected text. &Ctrl;&Shift;H EditFind Selected Backwards Finds previous occurrence of selected text. &Ctrl;G Edit Go to Line... This opens the goto line bar at the bottom of the window which is used to have the cursor jump to a particular line (specified by number) in the document. The line number may be entered directly into the text box or graphically by clicking on the up or down arrow spin controls at the side of the text box. The little up arrow will increase the line number and the down arrow decrease it. Close the bar with a click on the button with an icon on the left side of the bar.

The Bookmarks Menu &Ctrl;B Bookmarks Set Bookmark Sets or removes a bookmark in the current line of the active document. (If it is there, it is removed, otherwise one is set). Bookmarks Clear All Bookmarks This command will remove all the markers from the document as well as the list of markers which is appended at the bottom of this menu item. &Alt; PgUp BookmarksPrevious This will move the cursor to beginning of the first above line with a bookmark. The menuitem text will include the line number and the first piece of text on the line. This item is only available when there is a bookmark in a line above the cursor. &Alt; PgDown BookmarksNext This will move the cursor to beginning of the next line with a bookmark. The menuitem text will include the line number and the first piece of text on the line. This item is only available when there is a bookmark in a line below the cursor. At the bottom of this menu, a list of bookmarks appears if any bookmarks are available for this window. The Tools Menu Tools Read Only Mode Set the current document to Read Only mode. This prevents any text addition and any changes in the document formatting. Tools Mode Choose the filetype scheme you prefer for the active document. This overwrites the global filetype mode set in Settings Configure Editor... in the Filetypes tab for your current document only. Tools Highlighting Choose the Highlighting scheme you prefer for the active document. This overwrites the global highlighting mode set in Settings Configure Editor... for your current document only. Tools Indentation Choose the style of indentation you want for your active document. This overwrites the global indentation mode set in Settings Configure Editor... for your current document only. Tools Encoding You can overwrite the default encoding set in Settings Configure Editor... in the Open/Save page to set a different encoding for your current document. The encoding you set here will be only valid for your current document. Tools End of Line Choose your preferred end of line mode for your active document. This overwrites the global end of line mode set in Settings Configure Editor... for your current document only. Tools Add Byte Mark Order (BOM) Checking this action you can explicitly add a byte order mark for unicode encoded documents. The byte order mark (BOM) is a Unicode character used to signal the endianness (byte order) of a text file or stream, for more information see Byte Order Mark. &Ctrl;Space Tools Invoke Code Completion Manually invoke command completion, usually by using a shortcut bound to this action. Tools Word Completion Reuse Word Below (&Ctrl; 9) and Reuse Word Above (&Ctrl; 8) complete the currently typed text by searching for similar words backward or forward from the current cursor position. Shell Completion pops up a completion box with matching entries. &Ctrl;&Shift;O Tools Automatic Spell Checking When Automatic Spell Checking is enabled, wrong text is underlined in the document on-the-fly. ToolsSpelling... This initiates the spellchecking program - a program designed to help the user catch and correct any spelling errors. Clicking on this entry will start the checker and bring up the speller dialog box through which the user can control the process. There are four settings lined up vertically in the center of the dialog with their corresponding labels just to the left. Starting at the top they are: Unknown word: Here, the spellchecker indicates the word currently under consideration. This happens when the checker encounters a word not in its dictionary - a file containing a list of correctly spelled words against which it compares each word in the editor. Replace with: If the checker has any similar words in its dictionary the first one will be listed here. The user can accept the suggestion, type in his or her own correction, or choose a different suggestion from the next box. Language: If you have installed multiple dictionaries, here you can select which dictionary/language should be used. On the right side of the dialog box are 6 buttons that allow the user to control the spellcheck process. They are: Add to Dictionary Pressing this button adds the Unknown word to the checker's dictionary. This means that in the future the checker will always consider this word to be correctly spelled. Suggest The checker may list here a number of possible replacements for the word under consideration. Clicking on any one of the suggestions will cause that word to be entered in the Replace with box, above. Replace This button has the checker replace the word under consideration in the document with the word in the Replace with box. Replace All This button causes the checker to replace not only the current Unknown word: but to automatically make the same substitution for any other occurrences of this Unknown word in the document. Ignore Activating this button will have the checker move on without making any changes. Ignore All This button tells the checker to do nothing with the current Unknown word: and to pass over any other instances of the same word. This only applies to the current spellcheck run. If the checker is run again later it will stop on this same word. Three more buttons are located horizontally along the bottom of the spellcheck dialog. They are: Help This invokes the &kde; help system with the help page for this dialog. Finished This button ends the spellcheck process, and returns to the document. Cancel This button cancels the spellcheck process, all modifications are reverted, and you will return to your document. Tools Spelling (from cursor)... This initiates the spellchecking program but it starts where your cursor is instead of at the beginning of the document. Tools Spellcheck Selection... Spellchecks the current selection. Tools Change Dictionary Displays a drop down box with all available dictionaries for spellchecking at the bottom of the editor window. This allows easy switching of the spellcheck dictionary ⪚ for automatic spellcheck of text in different languages. ToolsClean Indentation This cleans the indentation for the current selection or for the line the cursor is currently in. Cleaning the indentation ensures that all your selected text follows the indentation mode you choose. Tools Align Causes a realign of the current line or selected lines using the indentation mode and indentation settings in the document. &Ctrl;D Tools Comment This adds one space to the beginning of the line where the text cursor is located or to the beginning of any selected lines. &Ctrl;&Shift;D Tools Uncomment This removes one space (if any exist) from the beginning of the line where the text cursor is located or from the beginning of any selected lines. &Ctrl;U Tools Uppercase Put the selected text or the letter after the cursor in uppercase. &Ctrl;&Shift;U Tools Lowercase Put the selected text or the letter after the cursor in lowercase. &Ctrl;&Alt;U Tools Capitalize Capitalize the selected text or the current word. &Ctrl;J Tools Join Lines Joins the selected lines, or the current line and the line below with one white space character as a separator. Leading/trailing white space on joined lines is removed in the affected ends. Tools Apply Word Wrap Apply static word wrapping on all the document. That means that a new line of text will automatically start when the current line exceeds the length specified by the Wrap words at option in the Editing tab in SettingsConfigure Editor... If the plugin Insert File is enabled, you will find here an additional menu item Insert File.... The Settings Menu Settings Configure Editor... This menu item opens a dialog whereby several different settings may be adjusted. The KrViewer Menu &Ctrl;&Shift; G KrViewer Generic viewer &krusader;'s internal viewer is actually part of &konqueror;, which can basically view every file type viewable by &konqueror; (⪚ display pictures, play music, show the content of an archive). &Ctrl;&Shift; T KrViewer Text viewer View the file in text mode. &Ctrl;&Shift; H KrViewer Hex viewer View the file in hex mode. &Ctrl;&Shift; L KrViewer Lister Fast text/hex viewer for huge filesizes, done by Krusader lister. &Ctrl;&Shift; E KrViewer Text editor Edit the file in text mode. &Ctrl;&Shift; D KrViewer Detach Tab Detach browsing Tab and open in a new window. &Ctrl; Q KrViewer Quit Closes &krusader;'s viewer/editor window. The Editor Component Configuration This group contains all pages related to the editor component of &kappname;. Most of the settings here are defaults, they can be overridden by defining a filetype, by Document Variables or by changing them per document during an editing session. Appearance General Dynamic Word Wrap If this option is checked, the text lines will be wrapped at the view border on the screen. Dynamic word wrap indicators (if applicable) Choose when the Dynamic word wrap indicators should be displayed, either Off, Follow Line Numbers or Always on. Align dynamically wrapped lines to indentation depth: Enables the start of dynamically wrapped lines to be aligned vertically to the indentation level of the first line. This can help to make code and markup more readable.Additionally, this allows you to set a maximum width of the screen, as a percentage, after which dynamically wrapped lines will no longer be vertically aligned. For example, at 50%, lines whose indentation levels are deeper than 50% of the width of the screen will not have vertical alignment applied to subsequent wrapped lines. Whitespace Highlighting Highlight tabulators The editor will display a » symbol to indicate the presence of a tab in the text. Highlight trailing spaces The editor will display dots to indicate the presence of extra whitespace at the end of lines. Advanced Show indentation lines If this is checked, the editor will display vertical lines to help identifying indent lines. Highlight range between selected brackets If this is enabled, the range between the selected matching brackets will be highlighted. Borders Borders Show folding markers (if available) If this option is checked, the current view will display marks for code folding, if code folding is available. Show icon border If this is checked, you will see an icon border on the left hand side. The icon border shows bookmark signs for instance. Show line numbers If this is checked, you will see line numbers on the left hand side. Show scrollbar marks If this option is checked the current view will show marks on the vertical scrollbar. These marks will for instance show bookmarks. Sort Bookmarks Menu By creation Each new bookmark will be added to the bottom, independently from where it is placed in the document. By position The bookmarks will be ordered by the line numbers they are placed at. Fonts & Colors This section of the dialog lets you configure all fonts and colors in any color scheme you have, as well creating new schemes or deleting existing ones. Each scheme has settings for colors, fonts and normal and highlight text styles. &kappname; will preselect the currently active scheme for you, if you want to work on a different scheme start by selecting that from the Schema combobox. With the New and Delete button you can create a new scheme or delete existing ones. At the bottom of the page you can select the Default schema for &kappname;. Colors Text Area Background Normal text This is the default background for the editor area, it will be the dominant color on the editor area. Selected text This is the background for selected text. The default is the global selection color, as set in your &plasma; color preferences. Current line Set the color for the current line. Setting this a bit different from the Normal text background helps to keep focus on the current line. Bookmark This combobox lets you set overlay colors for various mark types. The color is mixed into the background color of a marked line, so that a line with more marks or a marked line that is current has a background that is a mix of more colors. The mark colors are also used if you enable display of scrollbar marks. Additional Elements Left border background This color is used for the marks, line numbers and folding marker borders in the left side of the editor view when they are displayed. Line numbers This color is used to draw the line numbers on the left side of the view when displayed. Bracket highlight This color is used to draw the background of matching brackets. Word wrap markers This color is used to draw a pattern to the left of dynamically wrapped lines when those are aligned vertically, as well as for the static word wrap marker. Tab and space markers This color is used to draw white space indicators when enabled. Spelling mistake line sets the color of the line that is used to indicate spelling mistakes. Fonts Here you can choose the font for the schema. You can choose from any font available on your system, and set a default size. A sample text displays at the bottom of the dialog, so you can see the effect of your choices. Normal Text Styles The normal text styles are inherited by the highlight text styles, allowing the editor to present text in a very consistent way, for example comment text is using the same style in almost all of the text formats that &kappname; can highlight. The name in the list of styles is using the style configured for the item, providing you with an immediate preview when configuring a style. Each style lets you select common attributes as well as foreground and background colors. To unset a background color, rightclick to use the context menu. Highlighting Text Styles Here you can edit the text styles used by a specific highlight definition. The editor preselects the highlight used by your current document. To work on a different highlight, select one in the Highlight combobox above the style list. The name in the list of styles is using the style configured for the item, providing you with an immediate preview when configuring a style. Each style lets you select common attributes as well as foreground and background colors. To unset a background color, rightclick to use the context menu. In addition you can see if a style is equal to the default style used for the item, and set it to that if not. You will notice that many highlights contain other highlights represented by groups in the style list. For example most highlights import the Alert highlight, and many source code formats imports the Doxygen highlight. Editing colors in those groups only affects the styles when used in the edited highlight format. Editing General Static Word Wrap Word wrap is a feature that causes the editor to automatically start a new line of text and move (wrap) the cursor to the beginning of that new line. &kappname; will automatically start a new line of text when the current line reaches the length specified by the Wrap Words At: option. Enable static word wrap Turns static word wrap on or off. Show static word wrap markers (if applicable) If this option is checked, a vertical line will be drawn at the word wrap column as defined in the Settings Configure Editor... in the Editing tab. Please note that the word wrap marker is only drawn if you use a fixed pitch font. Wrap words at: If the Enable static word wrap option is selected this entry determines the length (in characters) at which the editor will automatically start a new line. Misc Remove trailing spaces while editing &kappname; will automatically eliminate extra spaces at the ends of lines of text. Auto brackets When the user types a left bracket ([, (, or {) &kappname; automatically enters the right bracket (}, ), or ]) to the right of the cursor. Copy/Cut the current line if no selection If this option is enabled and the text selection is empty, copy and cut action are performed for the line of text at the actual cursor position. Allow scrolling past the end of the document This option lets you scroll past the end of the document. This can be used to vertically centre the bottom of the document, or put it on top of the current view. Cursor & Selection Text Cursor Movement Smart home and smart end When selected, pressing the home key will cause the cursor to skip white space and go to the start of a line's text. Wrap cursor When on, moving the insertion cursor using the Left and Right keys will go on to previous/next line at beginning/end of the line, similar to most editors.When off, the insertion cursor cannot be moved left of the line start, but it can be moved off the line end, which can be very handy for programmers. When this option is chosen, moving the cursor with the arrow keys off the end of a line (to the right) causes it to jump down to the beginning of the next line. Likewise when the cursor is moved past the beginning of a line (to the left) it jumps up to the end of the preceding line. When this option is not selected, moving the cursor right past the end of a line merely causes it to continue horizontally in the same line and trying to move it left past the beginning does nothing. PageUp/PageDown moves cursor This option changes the behavior of the cursor when the user presses the Page Up or Page Down key. If unselected the text cursor will maintain its relative position within the visible text in &kappname; as new text becomes visible as a result of the operation. So if the cursor is in the middle of the visible text when the operation occurs it will remain there (except when one reaches the beginning or end.) With this option selected, the first key press will cause the cursor to move to either the top or bottom of the visible text as a new page of text is displayed. Autocenter cursor (lines): Sets the number of lines to maintain visible above and below the cursor when possible. Text Selection Mode Normal Selections will be overwritten by typed text and will be lost on cursor movement. Persistent Selections will stay even after cursor movement and typing. Indentation Default Indentation mode: Select the automatic indentation mode you want to use as default. It is strongly recommended to use None or Normal here, and use filetype configurations to set other indentation modes for text formats like C/C++ code or &XML;. Indent using Tabulators When this is enabled the editor will insert tabulator characters when you press the key or use automatic indentation. Spaces When this is enabled the editor will insert a calculated number of spaces according to the position in the text and the setting when you press the key or use automatic indentation. Tabulators and Spaces When this is enabled, the editor will insert spaces as describe above when indenting or pressing at the beginning of a line, but insert tabulators when the key is pressed in the middle or end of a line. Tab width: This configures the number of spaces that are displayed in place of a tabulator character. Indentation width: The indentation width is the number of spaces which is used to indent a line. If configured to indent using tabulators, a tabulator character is inserted if the indentation is divisible by the tab width. Indentation Properties Keep Extra Spaces If this option is disabled, changing the indentation level aligns a line to a multiple of the width specified in Indentation width. Adjust indentation of code pasted from the clipboard If this option is selected, pasted code from the clipboard is indented. Triggering the Undo action removes the indentation. Indentation Actions Backspace key in leading blank space unindents If this option is selected, the &Backspace; key decreases the indentation level if the cursor is located in the leading blank space of a line. Tab key action (if no selection exists) If you want to align the current line in the current code block like in emacs, make a shortcut to the action Align. Always advance to the next tab position If this option is selected, the key always inserts white space so that the next tab position is reached. If the option Insert spaces instead of tabulators on the General tab in the Editing page is enabled, spaces are inserted; otherwise, a single tabulator is inserted. Always increase indentation level If this option is selected, the key always indents the current line by the number of character positions specified in Indentation width. Increase indentation level if in leading blank space If this option is selected, the key either indents the current line or advances to the next tab position. If the insertion point is at or before the first non-space character in the line, or if there is a selection, the current line is indented by the number of character positions specified in Indentation width. If the insertion point is located after the first non-space character in the line and there is no selection, white space is inserted so that the next tab position is reached: if the option Insert spaces instead of tabulators on the General tab in the Editing page is enabled, spaces are inserted; otherwise, a single tabulator is inserted. Auto Completion General Enable auto completion If enabled, a word completion box automatically pops up during typing showing a list of text entries to complete the current text under the cursor. Minimal word length to complete While typing text, the word completion searches for words in the document starting with the already typed text. This option configures the minimal amount of characters that are needed to make the word completion active and pop up a completion box. Vi Input Mode General Use VI input mode When selected, the vi input mode will be enabled when opening a new view. You can still toggle the vi input mode on/off for a particular view in the Edit menu. Let Vi commands override Kate shortcuts When selected, Vi commands will override &kappname;'s built-in commands. For example: &Ctrl;R will redo, and override the standard action (showing the search and replace dialog). Hide the Vi mode status bar By default, an extra status bar will be used when the Vi input mode is enabled. This status bar shows commands while they are being typed and messages/errors produced by Vi commands. Checking this option will hide this extra status line. Key Mapping Key mapping is used to change the meaning of typed keys. This allows you to move commands to other keys or make special keypresses for doing a series of commands. Example: F2 -> I-- &Esc; This will prepend I-- to a line when pressing F2. Spellcheck These configuration options are described in the documentation for the &systemsettings; module Spell Checker. Open/Save General File Format Encoding: This defines the standard encoding to use to open/save files, if not changed in the open/save dialog or by using a command line option. Encoding Detection Select an item from the drop down box, either to disable autodetection or use Universal to enable autodetection for all encodings. But as this may probably only detect utf-8/utf-16, selecting a region will use custom heuristics for better results. If neither the encoding chosen as standard above, nor the encoding specified in the open/save dialog, nor the encoding specified on command line match the content of the file, this detection will be run. Fallback Encoding This defines the fallback encoding to try for opening files if neither the encoding chosen as standard above, nor the encoding specified in the open/ save dialog, nor the encoding specified on command line match the content of the file. Before this is used, an attempt will be made to determine the encoding to use by looking for a byte order marker at start of file: if one is found, the right unicode encoding will be chosen; otherwise encoding detection will run, if both fail fallback encoding will be tried. End of line: Choose your preferred end of line mode for your active document. You have the choice between &UNIX;, DOS/&Windows; or Macintosh. Automatic end of line detection Check this if you want the editor to autodetect the end of line type. The first found end of line type will be used for the whole file. Enable byte order marker The byte order mark is a special sequence at the beginning of unicode encoded documents. It helps editors to open text documents with the correct unicode encoding. For more information see Byte Order Mark. Automatic Cleanups on Load/Save Remove trailing spaces The editor will automatically eliminate extra spaces at the ends of lines of text while loading/saving the file. Advanced Folder Config File Search depth for config file: The editor will search the given number of folder levels upwards for &kappname; config file and load the settings line from it. Further information about these hidden folder config files you find in the document variables section. Backup on Save Backing up on save will cause &kappname; to copy the disk file to <prefix><filename><suffix> before saving changes. The suffix defaults to ~ and prefix is empty by default. Local files Check this if you want backups of local files when saving. Remote files Check this if you want backups of remote files when saving. Prefix Enter the prefix to prepend to the backup file names. Suffix Enter the suffix to add to the backup file names. Disable swap file syncing &kappname; is able to recover (most of) what was written after last save in case of a crash or power failure. A swap file (.swp.<filename>) is created after the first editing action on a document. If the user doesn’t save the changes and &kappname; crashes, the swap file remains on the disk. When opening a file, &kappname; checks if there is a swap file for the document and if it is, it asks the user whether he wants to recover the lost data or not. The user has the possibility to view the differences between the original file and the recovered one, too. The swap file is deleted after every save and on normal exit. &kappname; syncs the swap files on the disk every 15 seconds, but only if they have changed since the last sync. The user can disable the swap files syncing if he wants, by checking the Disable swap file syncing box, but this can lead to more data loss. Modes & Filetypes This page allows you to override the default configuration for documents of specified MIME types. When the editor loads a document, it will try if it matches the file masks or MIME types for one of the defined filetypes, and if so apply the variables defined. If more filetypes match, the one with the highest priority will be used. Filetype: The filetype with the highest priority is the one displayed in the first drop down box. If more filetypes were found, they are also listed. New This is used to create a new filetype. After you click on this button, the fields below get empty and you can fill the properties you want for the new filetype. Delete To remove an existing filetype, select it from the drop down box and press the Delete button. Properties of current filetype The filetype with the highest priority is the one displayed in the first drop down box. If more filetypes were found, they are also listed. Name: The name of the filetype will be the text of the corresponding menu item. This name is displayed in the ToolsFiletypes Section: The section name is used to organize the file types in menus. This is also used in the ToolsFiletypes menu. Variables: This string allows you to configure &kappname;'s settings for the files selected by this MIME type using &kappname; variables. You can set almost any configuration option, such as highlight, indent-mode, etc. Press Edit to see a list of all available variables and their descriptions. Select the checkbox on the left to enable a particular variable and then set the value of the variable on the right. Some variables provide a drop-down box to select possible values from while others require you to enter a valid value manually. For complete information on these variables, see Configuring with Document Variables. Highlighting: If you create a new file type, this drop down box allows you to select a filetype for highlighting. Indentation Mode: The drop down box specifies the indentation mode for new documents. File extensions: The wildcards mask allows you to select files by filename. A typical mask uses an asterisk and the file extension, for example *.txt; *.text. The string is a semicolon-separated list of masks. MIME types: Displays a wizard that helps you easily select MIME types. Priority: Sets a priority for this file type. If more than one file type selects the same file, the one with the highest priority will be used. Download Highlighting Files...
