Hello,

For Note based lyrics in the notation window, the font setting is found in the Notation Window Options.  For bar lyrics in the Chordsheet, the lyrics font setting is found in ChordSheet and display prefs.  (look to the right of the Choose Font button).  For the Leadsheet, it will use the Notation Window Options.  Big lyrics, cannot be changed.

You can begin playing the song in the Big Lyrics window by double clicking the bar you want the song to start playing at.

Thank you,
Catherine
