Hello,
Thanks for pointing that one out to me (I don't think I've ever used Shift + Space - at least not on purpose).
I will reword/update the description a bit, but keep the control at C
- it was primarily picked since it was also QuickSwap's default, and due to its convenient position on standard US keyboard layout - the idea being to use single keystroke that will be reachable in situation where WASD is preserved for movement controls.
Should people start complaining about too many accidents, I might end-up revisiting the default, we'll see how it goes.
Best regards,
Branko
