Crop Tool Hotkeys

Currently when using the crop tool, only the ALT key acts as a hotkey, it causes a resize to operate centrally to the crop area.

It would be brilliant if Alt + Scrollwheel enlarged and shrank the crop area around the centre, too. I have 5000 images to crop and grabbing those handles is destroying my already paperthin will to live.

Also perhaps X could swap the crop aspect orientation, instead of having to grab the handles ? Sadly aspect ratio presets don't honour orientation, so that isn't a viable workaround.

I've added crop rotation to the mousewheel (Like a speed edit) via AutoHotkey because that was something I wasn't able to live without, but I can't find a way to script these two holdouts.
