Saving and reverting layout changesAs you design a layout in Layout mode, save your work early and often. Don’t wait until you finish working. If you want to throw away the changes you’ve made and start again, you can easily revert to the last-saved version of a layout.

• You can use the undo and redo features to incrementally remove or replace changes on layouts (such as changes to field labels) and changes to objects (such as moving or resizing), up to the last 1,000 changes.
• You can set an application preference to save your layout changes automatically when you leave Layout mode. For more information, see Setting layout preferences.
