I am using LibreOffice 6.4.3.2 on Ubuntu 20.04. For some reasons, recently, PgUp and PgDn on my keyboard suddenly stopped working. This makes certain activities more challenging (e.g. creating screencasts). Under certain circumstances, I prefer to be in the normal mode, as the Presentation mode covers everything else, which I also need to use in, e.g. a screencast session. I checked my GNOME keyboard settings. I couldn’t detect any keyboard shortcut conflicts. So, any suggestions to restore the two shortcuts?
