Hot Key For Item Transfer (Inv -> Stash, Inv -> Sell, etc)

Hello, I'm in my early 30's and am experiencing some carpel tunnel and tennis elbow. Would it be possible to add a hotkey to transfer items instead of ctrl+click? I would like to bind it to space bar or tab. Of course, the mouse cursor would have to be on the item for it to transfer but the idea of stash sorting in a parent league wouldn't be such a pain if I didn't have to use a mouse.
