To display the History palette:
Choose Window > History, or click the History palette tab.
To revert to a previous state of an image:
Do any of the following:
Click the name of the state.
•
Drag the slider at the left of the state up or down to a different state.
•
(Photoshop) Choose Step Forward or Step Backward from the palette menu or the Edit
•
menu to move to the next or previous state.
To delete one or more states of the image (Photoshop):
Do one of the following:
Click the name of the state, and choose Delete from the History palette menu to delete
•
that change and those that came after it.
Drag the state to the Trash button
•
Choose Clear History from the palette menu to delete the list of states from the History
•
palette, without changing the image. This option doesn't reduce the amount of
memory used by Photoshop.
Hold down Alt (Windows) or Option (Mac OS), and choose Clear History from the
•
palette menu to purge the list of states from the History palette without changing the
image. If you get a message that Photoshop is low on memory, purging states is useful,
since the command deletes the states from the Undo buffer and frees up memory.
Important: This action cannot be undone.
Choose Edit > Purge > Histories to purge the list of states from the History palette for all
•
open documents.
Important: This action cannot be undone.
