In order to solve Users are not able to browse cbz files using the right arrow key (although it works for cbr files), two file types are recognized in KrServices::generateKrarcArchiveMimetypes().

ADDITIONAL INFORMATION

There's related information in:

• the code review Identify the "application/vnd.rar" MIME type in order to allow some operations, although there the changes are related to KrArcBaseManager::getShortTypeFromMime(const QString &mime), not KrServices::generateKrarcArchiveMimetypes().
• https://www.iana.org/assignments/media-types/application/vnd.comicbook+zip
• https://www.iana.org/assignments/media-types/application/vnd.comicbook-rar
• https://bbs.archlinux.org/viewtopic.php?pid=1656582#p1656582 , where it was said: The mime-type for "cbr" and "cbz" files changed with version 1.7 of shared-mime-info: https://cgit.freedesktop.org/xdg/shared-mime-info/diff/?id=Release-1-7

Note: cbz files are easily made, for example you simply compress some images to a zip file, change the extension of the zip file to "cbz", and that file can be viewed using e.g. Okular.

Browse several compressed files (cbr, cbz, rar, zip, 7z, etc.) using:

• the right arrow key,
• (in the case of cbr and cbz files) the secondary button of the mouse, and later choosing "Browse".
