Thank you, rharv...much appreciated!

Before I saw your reply, I discovered the following alternative method. (Your method sounds easier, though.) In Piano Roll view, right click on the note area and "select all notes". Then hover cursor to the left of any note and you will see the left-right movement arrows. Then, while holding down "Shift", use the left mouse button to drag the ensemble of notes to the left.
