Chapter 9 Working With Tracks 205
Hide Menu and Key Commands
There are a a couple of menu functions and key commands that relate to the Hide
Tracks feature.
Even when the global Hide View button is deactivated, you can still hide an individual
track with the View > Hide Current Track and Select Next Track command (default key
command: Control-H).
View > Unhide all Tracks (default key command: Shift-Control-H) will reset the Hide
buttons of each track, making them all visible.
Note: Hiding tracks does not affect their playback in any way. You can also link the Hide
functions of all tracks belonging to a group by selecting Hide in the Group Property
Settings (for further information on groups, see “
Working With Groups ” on page 562).
Another thing to keep in mind is that there is no Unhide Selected Arrange Track key
command because there is no way that you can select a hidden Arrange track—it is
hidden, after all …
Protecting Tracks
Tracks can be protected, thus preventing any alterations:
 Existing regions (and their contents) cannot be altered.
 No recording is possible on protected tracks.
 New regions cannot be created on protected tracks.
If the Track Protect button is not visible in the track list, you can switch it on via the
Track Header configuration window.
Clicking the Track Protect buttons toggles between locked and unlocked mode.
Command-clicking a Track Protect button in the track list will protect all tracks in the
currently-selected display level (or folder). If tracks were already protected, they will be
unprotected.
