I have a small problem with key Q. I had an idea to use lower case letter for items and uppercase for larger objects, like 'r' to read items in inventory and 'R' to read signs and stuff like that. But of course, 'q' is to quaff (funny word) potions and 'Q', well, that't the problem. It's most often used to quit the game, but in Kaduria it's handled in a game menu (F1). I could also use d/D (drink), but then how to 'd'rop items? Some of these command bindings are kind of standard in a way that changing them to some other would probably feel odd.
