Rebinding quick transfer (ctrl) to a different key

I use ctrl as roll button, and it closes trade windows when I press ctrl, so I can't quickly transfer items. Ability to rebind it to a different button would be very nice. Alternative would be to not close windows on roll and/or ability to disable continuous roll on button hold (so you hold ctrl and then enter transfer window)

Plus one to this request. As a left-handed I dodge roll using my thumb on right CTRL.

Not being able to rebind this function is really annoying

Thanks for the amazing job on the game
