Hi all, thank you for this thread! I keep forgetting how to enter bar lyrics.

If anyone else is in the same boat, here's how, extracted from the video that Noel referenced above.

1) Be sure you are in (normal) “Chord Sheet” view
2) Select with your cursor the first bar you want to add a lyric to
3) Choose Views: Chord Display >> Layers >> Bar Lyrics
4) A space will open up above the selected chord, where you can input text.
