100 Chapter 3 Arrange Window
If the Track Protect button is not visible in the Track List, you can switch it on via the
Arrange menu View > Track Protect Buttons. Clicking on the Lock button(s) toggles
between locked and unlocked mode.
If you hold Command while clicking on a Track Protect button in the Track List, all
tracks in the currently-selected display level (or folder) are protected. If they were
already protected, they will be unprotected.
Arrange Channel Strip
The channel strip of the currently selected Arrange track will appear in the Parameters
area of the Arrange window, provided that there is sufficient space to display it.
If there is not enough vertical room, click the upper left triangles in the Region
Parameter and/or Object Parameter boxes and/or hide the Toolbox (View > Toolbox).
Note: The Channel Strip Only option in the View menu (and key command) allows you
to hide all elements of the Parameters area — except the Arrange channel strip.
