I find the current use of numbers (1,2,3 etc) as shortcuts for the Tools quite unhelpful.
I have learned them mostly now, but it would be sensible (wouldn't it?) to map the keys to a helpful letter? O=oil, P=paint, A=airbush etc etc.
I would have found that very helpful as a new user.
Is there a way to change the keyboard mapping in ArtRage?
