Current behavior

hotkeys.addShortcut({keys: 'alt..'})  // how to specify hotkey of alt + .

Expected behavior

Hotkey Combo = alt + .

Minimal reproduction of the problem with instructions

Does nothing and can't seem to find a way to do it out of the box.

hotkeys.addShortcut({keys: 'alt..'});

What is the motivation / use case for changing the behavior?

Would be nice to include '.' character in hotkey combination.
