I’ve spent the past few days copying across around 40 songs, the vast majority of which were in cut time. The songs all had chord symbols, almost all of which were above either quarter, half or whole notes (I think just a couple were above eighth-notes).
The songs in 4/4 time were simple for Chord Entry, I just had to use the indent or space bar to shift position. Cut time was different - those keys only enabled access to notes on the beat; quarter notes either side of the beat could only be accessed by using the arrows. That made it a three key process and one that inevitably required hitting the arrow keys twice (as above, eighth-notes were rarely used). All in all, more fiddly.
I suspect it was done this way by design - the thinking being that chords generally appear on the beat. Bearing in mind that is a generalisation, I think that’s true of 4/4 (and 3/4) - but it’s not true of cut time when there were many (hundreds) of examples of chords appearing off the beat.
Personally, I found myself wondering whether the space bar should progress Chord Entry to the next beat, or the next quarter note. In cut time, the latter approach would certainly make entry easier.
