It works

I thought a fun little Xmas project would be to add a virtual numeric keypad to a ten-keyless keyboard. In my case, the DROP CTRL. But it should work with any 87 or 88 key keyboard (i.e., has the insert/delete/.../PgDn cluster and cursor keys). I chose a TKL over a full width keyboard because I don't need the numpad all that much and having it there pushes my mouse too far to the right to my taste. Should I really need a numpad for a few hours, I'd use a different keyboard. If I should ever need one very often, I'd get a separate numpad so I can put it whereever I want. But... there are times where this is overkill and it's still nice to be able to type numbers a bit more easily than using the number row. I'm a pretty good touch typist but using the number row is still a bit too error prone. Especially when copying numbers from paper or another window so you're not looking at what you're typing. Ok, so what's the deal? Simple: create a layer with the following key...
