LOL, I know what you mean. It takes some getting used to.
Some of the stuff I use everyday I can't explain because I don't think about it. I have to go back and do it so I can explain how it works.
I have a 7 button mouse thats mapped for almost everything I need.. Some of them are double mapped with the shift key so I could actually map 14 buttons, buttons but so far I haven't need that many.
Its a strange process because the "thinking" part of my brain is paying attention to the drawing. The "doing" part just knows what to do with the buttons. It doesn't talk to the "thinking" side much though. LOL So I have to do it and pay attention to what I'm doing to explain it.
