Tip:
Shift-clicking a note in the Note pop-up menu adds the value of the previously
displayed note to the value of the newly selected note. For example, if a
quarter note (1 beat) is already displayed, Shift-clicking and selecting the half
note (2 beats) will actually enter a duration value of the quarter note added
to the half note—in musical terms, this is a dotted half note and gets a total of three beats.
