The Snap menu setting applies to the following edit operations:

µ
Hold Control while performing the editing operation.
The division value chosen in the Transport bar (1/16, for example) determines the editing
grid scale.
µ

The editing grid switches to ticks.
Selecting Notes in the Piano Roll Editor
You must select note events before you can edit them. The usual selection
methods—clicking, Shift-clicking, and dragging with the Pointer tool—also apply to the
Piano Roll Editor.
The following selection options—unique to the Piano Roll Editor—are also available:
To select all notes of the same pitch in a MIDI region
µ
Click the corresponding key of the onscreen keyboard.
This is similar to selecting all regions on a track lane, by clicking the track name.
To select a range of note pitches in a MIDI region
µ
Click-drag over the key range of the onscreen keyboard.
All MIDI notes that fall within this pitch range are selected.
The info display shows the number of selected notes. The MIDI region name is shown
beside the number of selected notes. For example, 3/Piano means three notes are selected
from a MIDI region called Piano.
When you select multiple overlapping notes, the info display shows the chord name.
