Jumps and markers are used to create repeated sections in a score.
Use one of the following methods
If you select a jump or marker its playback properties can be viewed in the "Jump" or "Marker" section of the Properties panel.
In the case of jumps, you can see the titles of the markers that playback subsequently jumps to. These default settings should work for most users, but you can change the destination markers if desired, as long as the named objects exist in the score.
You can also specify whether repeats are taken or not in the section jumped to, by checking/unchecking "Play repeats"
For markers, you can view and edit the title of the marker only.
See also, Text properties.
You can change the default text properties of all repeat signs of a particular text style (either "Repeat text left" or "Repeat text right") in Format→Style→Text Styles.
