Red symbol S and N

[Remyannio]

What is the use of the red symbols S and N ?

[pdxdjazz]

Using the SMALL (red S) and NORMAL (red N) allows you to make the chords display in a smaller font on the chart, and then return them to normal size.
This is useful when there are multiple chords in a single measure and they display on-top of each other. Position the cursor on the first chord you wish to make smaller and click SMALL. That chord and all following chords will be made small. Then move forward to where you wish to restore the chords to normal size and click NORMAL. This can be done multiple times in a chart as needed. The red S and N only appear in the editor.
Hope this helps,
