I often find that I use the ruler tool to indicate a direction for a player. But, then I find that I can't select a token, and realize that I have to re-choose the select tool. It would be nice if: A) Each tool had a hotkey (like alt-s for the select tool and alt-r for the ruler tool) B) One tool could be assigned a modifier key (for example, so that I could draw a ruler arrow while holding the control key, but then go back to my previously selected tool once I release control)
