Undo

Every change saves at once, and most can be taken back.

Undo

Press ⌘ + Z to undo the last action. Press it again to go further back. ⇧ + ⌘ + Z brings it back. On Windows it is Ctrl+Z, and Ctrl+Y brings it back.

Edits in the track card are undone the same way. Text you typed or pasted in a field goes away with one ⌘ + Z.

While you are typing in a field, ⌘ + Z first takes back your typing. When there is nothing left to take back there, it undoes the action before.

After moving or deleting many tracks, an Undo card appears for a few seconds, with the time left on it. Click it to take the action back. The card waits while your pointer is on it.

Two tracks deleted, then Undo on the card that appears.
