They probably didn’t have a clue what keys to use, so they figured to come up with this in a hurry, where number keys are likely already in use through an existing in-game mechanic. For some reason I am actually no longer amazed, leaving it to us to figure out instead…
Why even 1 and 3, leaving a gap, and not 1 and 2, leaving us 3 to 0? With the choice to use number keys, they should have limited the in-game mechanic at the same time. Then they should have removed/defaulted whatever was currently assigned by us.
Pfffttt, there is a full keyboard to pick keys from, but let’s pick some numbers, so the player will notice? Then just add these to the config menu, where pretty much anyone in their right mind will pick ANYTHING BUT a number key. The choice is yours… problem solved?
Out of curiosity, can anyone tell me how this works on a controller (PS4/Xbox One)? And is there a similar way to assigning 0-9 in-game (quick menu) on a controller?
