Have interact and attack/throw be different keys(PC)

[odizzido]

It would be nice if PC players could have a different key for interacting, such as picking up items, opening doors, etc. Currently I am constantly throwing rocks at bunnies that are already stunned as I try to pick them up. I know on console you have a limited number of buttons but on PC we really shouldn't have to deal with problems like that.

Ideally you would have a system as good as quake 1 where you bind commands to any key, bind multiple keys to the same command, bind multiple commands to the same key, etc. It's a solved problem already, just copy the exact same system from quake 1.
