Rehearsal marks
The following types of rehearsal marks are available: numbers and letters.
When you place the first of these in the score, it is labeled 1 or A (depending on which you choose), the second is then automatically labeled 2 or B, the next 3 or C, etc. If you delete one, the labeling of the others is shifted automatically so that they always make up a complete series of numbers or letters.
You can select a font and size for rehearsal marks in the Project Text section of the Project–Font Settings subpage in the Score Settings dialog.
Use the Frame option to add a box or an oval around the rehearsal mark.
Rehearsal marks can be added automatically at the start position of each Marker in the project with the “Marker track to Form” function.
