Undo History Panel in Photoshop Elements 10

Elements takes the Undo command to new levels by offering you the Undo History panel on which all (well, almost all) your changes in an editing session are recorded and available for undoing at any step in an editing sequence.

Each edit you make is recorded on the Undo History panel. To open the panel, choose Window→Undo History. Make changes to your document, and each step is recorded on the panel.

If Elements slows down and you’re moving along at a snail’s pace, choose Edit→Clear→Undo History or choose Clear Undo History from the panel’s Options menu. Elements flushes all the recorded history and frees up some precious memory, which often enables you to work faster. You can also use Edit→Clear Clipboard or Edit→Clear→All to eliminate Clipboard data from memory.

Almost all steps are recorded, because the number of steps the History panel can record is controlled by a preference setting that tops out at 1,000 steps. If you choose Edit→Preferences (Windows) or Photoshop Elements→Preferences (Macintosh) and look at the Performance preferences, the number of history states (times you can go back in history and undo) defaults to 50.

You can change the number to the maximum of 1,000, if you like. But realize that the more history states you record, the more memory Elements requires.

When you want to undo multiple edits, open the Undo History panel and click any item listed on the panel. Elements takes you to that last edit while scrubbing all edits that follow the selected item. If you want to bring back the edits, just click again on any step appearing grayed out on the panel to redo up to that level.

All your steps are listed on the Undo History panel as long as you remain in Elements and don’t close the file. When the file is closed, all history information is lost.
