Backspace, arrow keys suddenly stopped working, what do I do?

Hi all,

thanks for taking the time to reply. I have slowly gotten used to using Office Libre and moved up to ver 6, but suddenly my keys (backspace, arrow keys etc) stopped working. Sometimes when I open a new document the work at first but then stop. So I went back to ver 5 and it’s the same. Help, what have I done? I check the app data and deleted the user file, check the keyboard shortcuts to make sure I haven’t done anything there but still not working?

Be grateful if anyone can figure this out, as a cursory search hasn’t helped to solve it so far.

Please edit your question to include basic and essential information. Are these keys working in other applications? what operating system? etc. Thanks.
