Keyboard Shortcuts for Sharpen AI

I’m often moving the zommed section of an image slightly to find the best part for a preview. To avoid time consuming calculations when moving, I switched the auto update feature off. Once I’m happy with the section for a preview, I have to click ‘Update’ with the mouse to see the result.

I’d prefer to have a keybord shortcut to start the calculation, i.e. “U” for “Update”.
There may be more situations where a keyboard shortcut could improve using Shapen AI easier.
