Using the History Palette
You can use the History palette to revert to a
previous state of an image, to delete an image's
states, and in Photoshop, to create a document
from a state or snapshot.

To display the History palette:
Choose Window > Show 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.
E F G
• (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 ( ) to delete
that change and those that came after it.
• 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.
