Recently the keyboard shortcuts have started to look strange. I can see all the letters alright but other symbols like ">" for File/Recent projects, or generally the Command-symbol are missing (shortcut for Open file... is only "O" rather than "Command O").
Have tried to reinstall and tried to restart after removing settings according to instructions here
