/*
    I just got a bright idea... Why not make a simple text editor?!
    I mean... When you just have no other way - better than nothing
    Add a nice rolling number wheel for faster linenumber input
    Basically 0-9 repeated, select saves digit. Oh, also empty
    or otherwise denoted spot for finishing teh num input
