Quick Undo & Redo
Ctrl+Z undoes your last change (⌘Z on a Mac). Ctrl+Y or Ctrl+Shift+Z redoes it; on a Mac, ⌘⇧Z or ⌘Y. The app menu has Undo and Redo at the top, and search has both as commands. A row or cell that comes back flashes, so you can find it on a long list.
What Undo Covers
Most edits go on the history, call sheet edits included.

Deleted Rows Come Back as Themselves
Undoing a delete puts the row back under the id it had. Anything that pointed at it still points at it, and redo can delete it again cleanly. Deleting a department unassigns everyone in it. Undo brings the department back and files those crew members under it again. Deleting a BG role group works the same way: the performers who were in it go back into the group. The restore is safe to repeat. Undoing twice will not create a duplicate.
Days Are the Exception
Undoing a deleted day puts the day back and restores the numbering of the days around it. The call sheet that was on that day does not come back. It was deleted with the day.
Where the History Lives
There is one history for the session, holding your last 50 changes. It is not split by tab. Press Ctrl+Z on the Cast tab and it reverses the last thing you did, even if that was on Crew a minute ago. While a text field has the cursor, Ctrl+Z undoes your typing in that field. Click outside it to reach the history.
A Caution on Collaboration
An undo is an edit like any other. It is saved and sent to everyone with the show open, and most undos are written into Change History too. Two kinds of undo are careful about other people. Undoing who is on a day replays only your change on top of the day as it stands now, so a colleague's scheduling on the same day survives. An undo on the PR Front grid touches only the cells your edit touched. Most other fields just get the old value written back. If a collaborator has changed that same field since, your undo overwrites them. With two ADs in the show, check what has moved before undoing something from twenty minutes ago.
