Almost all operations in the Notation Editor act on the selected notes and symbols. You can select these objects in different ways:
- With the computer mouse
- With the keyboard’s navigation keys
- With the navigation keys next to the Piano Roll or with the controls in the menu bar
You can select multiple things with the keyboard navigation keys, by selecting
[Shift]-[↑/→/↓/←], just like many applications. There is a similar control for selection in the menu bar. Some operations, like changing the pitch for example, act on all the selected notes.
Sometimes a selection of one line affects all the bars/measures in the system.
When you change the key, for instance, the selection determines where the key change starts. If you have multiple bars/measures selected, it applies to those bars/measures, and then changes back to whatever it was before.
