Every OS:
- Assigning the key '<' (between LSHIFT and Y on a german qwertz keyboard) to an action will have it show up as NONE, but it will work until the next game start. After that, it will be reset to its default assignment.
- Can't assign an action to the key '^' (above TAB, left of '1') either.
Mac only:
- Attempting to assign something to the ` (grave) key will instead assign it to 'circumflex', which isn't on a Mac's keyboard.
