[Feature Request] Restore ability to input effects using number pad

[ZeroJanitor]

Vanilla Famitracker and 0CC-Famitracker both had the ability to input effects that use numbers (such as 4xy) using either the top number row on the keyboard or using the number pad that many keyboards have.

However, this functionality was mysteriously absent from j0CC. I would love to see this restored if at all possible, as it's basically the only reason I'm reluctant to switch from 0CC.
