This action changes the duration of notes in a variety of ways. 

Click on the image below for details about each control:

Note: Changing the duration from this page changes the performed duration, but may not change the notated duration. If the note carries into another note of the same voice, the following note will not be moved and it's possible that the note will be displayed in the score unchanged. If you want the following notes to "make room" for the new duration, see the topics on changing the duration using the Performance tab or on Moving elements using the actions tab.
