Mouse binds for keyboard controls

Being able to use the keyboard controls with just the mouse would be nice. For example, being able to move the selection with right click or cancel with middle click. They could be hardcoded or specifiable via flags, I just find needing to use mouse and keyboard to take a screenshot annoying.

I would do keyboard + mouse controls too. You drag it with arrow keys. or if youre a gamer, WASD. Or if youre a Leauge Of Legends player, <insert LOL controls here">.
