To save your changes, select one of the following options in the Save drop-down:
- Save - Save the app.
- Save & verify data - Save the app and verify that it is runnable based on external dependencies.
To undo an edit, click Undo (left arrow to the left of the Save drop-down) or use Ctrl-Z on PC or ⌘Z on Mac.
To redo an edit that you've undone, click Redo (right arrow to the left of the Save drop-down) or use either Ctrl-Y/ Ctrl-Shift-Z on PC or ⌘Y/ ⌘Shift-Z on Mac.
You can undo and redo changes only between saves. If you want to recover to an older saved version you can use version history instead.
By default, the last 10 changes are kept in Undo/Redo history. You can configure this number to any value between 0 and 100. See Configure app editor settings.
