I have a number of AutoHotKey/Hammerspoon numpad shortcuts for arranging windows.

In Visual Studio, on the suggestion of a colleague at my first job, I use Numpad + for copy, Numpad - for cut, and Numpad * for paste. (I've never managed to train my hand eye coordination to use these in any other program. Which is a bit of a shame, because they're actually pretty useful. Whichever side you mouse on, you can find some way of hitting them without much effort.)

The numpad also comes in handy sometimes for typing numbers.
