This dialog lets you edit the properties of an existing section, including its start position, length, repeat count, and name. To edit a section's properties, position the chart view's cursor anywhere within the section, and use Edit/Section/Properties or select Section/Properties from the chart view's context menu.
Start
This is the section's start position, in measures, beats, and ticks. Note that measures and beats are one-origin, i.e. the beginning of the song is 1:1:0. The start position is rounded as needed so that section begins on a chord boundary.
Length
This is the section's length, in measures, beats, and ticks. The length is rounded as needed so that section ends on a chord boundary.
Repeat
This is the section's repeat count. A section with a repeat count greater than zero loops the specified number of times, unless it's exited prematurely via the Next Section command. A section with a repeat count of zero loops forever, or until it's exited via the Next Section command.
Name
This is the section's optional name. The name appears in the Section List dialog but is otherwise unused.
