Pro Tools Reference Guide528
Clip Gain Info Shows the Clip Gain Fader icon at
the beginning of the clip, in the lower left corner. If
the clip uses static clip gain, the static Clip Gain
value (–144 dB to +36.0 dB) for a clip is displayed
to the right of the Clip Gain Fader icon. For a clip
that has dynamic clip gain (using breakpoint gain
settings), the Clip Gain value is not shown. For
more information, see “Clip Gain Info View” on
page 599.
Multiple Undo
Pro Tools can keep track of up to 32 of the last un-
doable operations, allowing you to return to a pre-
vious editing state.
The Undo operations in Pro Tools are stored in a
queue, in the order in which they were invoked.
When choosing
Edit > Undo, the most recent oper-
ation is undone. If you choose
Undo again, the next
operation in the queue is undone. You can also
choose
Edit > Redo to redo an operation, which
moves back through the Undo queue by one step.
When the number of operations in the Undo queue
reaches the maximum specified level of Undo (set
in the Editing Preferences page), performing an-
other undoable operation will remove the oldest
operation at the top of the queue.
To undo the last operation, do one of the following:
 Choose Edit > Undo.
 Press Control+Z (Windows) or Command+Z
(Mac).
To redo the last undone operation, do one of the
following:
 Choose Edit > Redo.
 Press Shift+Control+Z (Windows) or
Shift+Command+Z (Mac).
Undo History Window
You can use the Undo History window to view the
queue of the undoable and redoable operations and
return to any previous state. The Undo History can
show edit creation times, enabling you to revert to
the state a session held at a particular time.
To show (or hide) the Undo History window:
 Choose Window > Undo History.
To undo operations in the Undo History window:
 Click the operation (bold) in the list to undo.
All operations in the queue that were performed af-
ter the operation you select are also undone. In the
Undo History window, undoable operations are
shown in bold and redoable operations (operations
that have already been undone) are shown in ital-
ics.
If no actions are available to undo, the menu
displays Can’t Undo.
If no actions are available to redo, the menu
displays Can’t Redo.
