Just started using LibreOffice… In Writer/Tools/Customize, I see the keyboard shortcuts.
Is there a document I can download/print out that has a complete listing?
I would find this very helpful!
If not, should I create one for the community?
There is such a document, as always Help is useful, a search for shortcut reveals Shortcut Keys for LibreOffice Writer
You might find the Writer Guide of assistance, download from English documentation | LibreOffice Documentation - LibreOffice User Guides
