I disagree. [Modifier] + C & [mod] + V works just as good as a dedicated button and you are using the space more efficiently by having multiple uses for one key.
Keyboard already has a lot of buttons. We should be considering which to remove, not any additions
I support the number pad as well. I type in numbers into spreadsheets often enough that it’s useful for me.
If we were to delete, I’d say get rid of the F1 keys, get rid of Home / End, get rid of Num lock, etc.
