Hi,
Bizarre issue here:
I imported customized keyboard shortcuts from a different machine running same LO version (5.3). The two machine run Ubuntu.
The import was performed by going to Tools> Customize> Load and selecting the ‘Writer’ radio-button.
As a result my arrow keys and delete key on my brand new keyboard are disabled in Writer.
LO packages other than Writer show no issue.
This happens for ALL writer documents, old and new, before and after reboot.
How do I recover from that ? … I mean, short of purging and reinstalling the whole shenanigans ? Can I selectively reset Writer, its profile or a file functionally equivalent to a profile ?
Any help appreciated.
EDIT:
In addition I just purged my system from Libreoffice modules
     sudo apt-get remove --purge libreoffice*
and presumably config files and reinstalled it. That was a total of about 337 MB of storage space.
I relaunched  LO after reinstall and checked the Recent document option on the left pane of the LO window, EXPECTING not to see anything inside. All my previously opened docs were still there. How is that possible ?
So the purge did not work.
How can I fix that and have a functional keyboard in Writer again ?
