Actions are plug-in effects for changing music. Sometimes you might want toUse an action to transpose and move notes, or perhaps you'd like to merge 2 staves into a single Grand Staff. Other times, however, you might simply want to experiment with the music. Actions are good way to accomplish both tasks.
Actions are always applied to the current selection. As the selection changes, so does the set of possible actions that can be applied. The Actions tab in the Properties Palette displays all actions possible for the current selection. Just as the Properties Palette changes as the selection changes, so too do the contents of the Actions tab.
Whenever there are any actions available for the current selection an Actions menu appears next to the Music menu. When you select an item from the Actions menu the appropriate form in the Properties Palette is displayed.
