In trying to figure out how to detect if a key was relevant, I appended all the keycodes for keys on my keyboard that would "delete" selected text, and sorted. Generated the range blow:
Deleting
8, 9, 13, 46, 48-57, 65-90, 96-111, 186-192, 219-222

I did the same thign with keys that wouldn't and got these below
Not harmful
16-19, 27, 33-40, 45, 91-93, 112-123, 144

You should note, since it's onkeydown it doesn't change the code if you have alt or ctrl or something pressed. It makes it fewer keycombos actually.

I'm pretty sure in these "deleting" keys will still "delete" if shift is held
