Clearing the Undo Queue
To manually clear the Undo Queue

Click the
Options pop-up menu and choose
Clear Undo Queue.
Other operations that clear the Undo Queue include:
• Deleting a track, or clearing a clip from the Clips List
• Selecting Select > Unused, or Select > Unused Audio Except Whole Files in the Clips List menu
When the number of operations in the Undo History reaches the maximum level of Undo, performing another undoable operation removes the oldest operation at the top of the Undo History queue. When the oldest operation is one operation away from being pushed out of the queue, it is shown in red.
