The (left) meta key is useful to me, because it's one that is not bound to many keys. However, sometimes (randomly) shortcuts break! Let's list all my shortcuts: Ctrl+Shift+Meta+Arrow: Broken Ctrl+Meta+Arrow: Working Ctrl+Shift+Meta+S: Working Meta+[, ' and ;: Working Meta+F: Working Meta+Shift+PrintScr: Broken Meta+PrintScr: Working PrintScr: Working There does not seem to be a pattern, although Shift does seem more likely to break.
