Multiple Undo - DigiDesign Pro Tools 8.0 Reference Manual

Multiple Undo

Pro Tools can keep track of up to 32 of the last
undoable operations, allowing you to return to a
previous 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 op-
eration 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), per-
forming another undoable operation will re-
move the oldest operation at the top of the
queue.
To undo the last operation, do one of the following:
Choose Edit > Undo.
– or –
Press Control+Z (Windows) or Command+Z
(Mac).
If no actions are available to undo, the
menu displays Can't Undo.
To redo the last undone operation, do one of the
following:
Choose Edit > Redo.
– or –
Press Shift+Control+Z (Windows) or
Shift+Command+Z (Mac).
If no actions are available to redo, the menu
displays Can't Redo.
