Sort A–Z

Arrange can alphabetize at three levels:

To sort…	Do this
One folder	Double-click the folder, then click Sort A–Z in the folder card.
One page	Click A–Z in that page's header.
Everything	Click Sort all A–Z in the header.

Sort all A–Z sorts every page's apps and folders from A to Z. The Dock stays as it is, widgets stay on their pages, and empty pages are tidied away.

Sorting is just another change, so Undo (Cmd+Z) puts things back if you don't like the result.
