Double-click the Tie Tool on the Simple Entry Palette,
then click the first note to be tied. If the first note is selected, press
T. If the second note is selected, press SHIFT+T. A tie appears.
If you click the stem of a chord, a tie appears on every note in the chord;
if you click a single notehead, only that note receives the tie. Remove
a tie by clicking the note or chord again.
