Apple Logic Pro 9 - Manual (Page 251)

3 Click the global Hide View button, and all tracks whose Hide buttons have been activated
disappear from the Arrange window.
The H in the global Hide View button is highlighted, indicating that one or more tracks
(with active Hide buttons) are hidden.
To show hidden tracks
µ
Simply reactivate the Hide View button when you want to see the hidden tracks again.
There are also 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 (or use the
corresponding key command, default assignment: Control-H).
The View > Unhide all Tracks command (or the corresponding key command) 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 more information on groups, see
Working with Mixer Groups .) Keep in mind
that there is no Unhide Selected Arrange Track key command because there is no way
that you can select a hidden Arrange track.
Protecting Tracks in the Arrange Area
Tracks can be protected, to prevent any alterations. When a track is protected:
• Existing regions (and their contents) cannot be altered.
• No recording is possible.
• New regions cannot be created.
If the Track Protect button is not visible in the track list, you can display it using the Track
Header Configuration dialog.
