SinglePlayer

Are there any keypad users out there that don't have an escape button on their gamepad having to use 2 keyboards? May we please have a change to the controls for the escape button for exiting all sorts of stuff during the game. Can we just right click the mouse button for exiting these simple type of things. Or at least give us the option to change that in the control binds. I guess I could always resort to using voice attack or something along those lines.
