In Krusader you can move between widgets both with two configurable shortcuts "Focus up/down" (default : CTRL+SHIFT+UP/DOWN) and with an hardcoded CTRL+UP/DOWN, but neither can move through all the widgets.
This patch drops the hardcoded version in favor of the configurable one letting all widgets to be focused in sequence, all the unneeded code is removed.
The documentation is changed with the new shortcuts.
FIXED: [ 414831 ] cant focus embedded terminal with ctrl+down
