Slight change - it will be L to add Lyric or chord, so it will also work when entering notes from the PC keyboard (E is then used for a note, of course)

Also added S (start of repeat) and T (End of repeat)
And of course R for a rest, length will be as for the current note setting.

Captured tunes will automatically be given key signature of C (Partly because all accidentals will be played in, not implied.)

If there are no more requests for additions to this feature, I will go ahead and package it up for test.
