As a player, I do not want to reach from one end to another to just click a button in order to use that key.
Personally I never use "Spacebar" at all.
Is there a possibility of at least switching between the 2 keys in the options menu like what Relic did with hotkey set "classical and new"?
It would simply be great

Toggle the option button for either having it on spacebar or not to activate tactical map.
