ps

There is a bit of help if you go to Opt., Preferences, Display. Click on the Help button. It says this under New line for every section (part marker)

When set, most part markers will start a new line on the chord sheet. This makes the sections more readable. It can be disabled for a song using Edit | Settings (for This Song).

[There is also another checkbox having to do with the gray bars at the end of the song.]

However, I did not find anything in the Help, Index menu system about the gray bars.
