Keyboard Shortcuts - differentiate between numeric keypad and standard numbers

[Aammppaa]

By default the number keys set opacity - which is fine. BUT AD doesn't distinguish between the standard numbers and the numeric keypad, to which I'd really like to assign a bunch of other shortcuts.

 

With 15 keys on the numpad, and at least 3 different modifiers, there are >45 keyboard shortcuts going to waste here!

 

Also, under the current system, if I do set a numeric keypad numeral as a shortcut, it doesn't warn me that there is an existing clash with the opacity function... worst of both worlds!

 

Thanks for your consideration.
