User Guide
• By default, selecting a state dims those below.
This way you can easily see which changes will be
discarded if you continue working from the
selected state. (See “To specify history options:” on
page 170.)
• By default, selecting a state and then changing
the image eliminates all states that come after.
• If you select a state and then change the image,
eliminating the states that came after, you can use
the Undo command to undo the last change and
restore the eliminated states. (See “Correcting
mistakes” on page 167.)
• By default, deleting a state deletes that state and
those that came after it. If you choose the Allow
Non-Linear History option, deleting a state deletes
just that state.

To display the History palette:
Choose Window > Show History.
To revert to a previous state of the 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.
• Choose Step Forward or Step Backward from
the pop-up menu to move to the next or
previous state.
• Press Shift+Ctrl+Z (Windows) or
Shift+Command+Z (Mac OS) to move to the
next state.
• Press Alt+Ctrl+Z (Windows) or
Option+Command+Z (Mac OS) to move to the
previous state.
To delete one or more states of the image:
Do one of the following:
• Click the name of the state, and choose Delete
from the pop-up menu on the palette 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 pop-up menu to
delete the list of states from the History palette,
without changing the image.
• Hold down Alt (Windows) or Option (Mac OS)
and choose Clear History from the pop-up menu
to purge the list of states from the History palette
without changing the image. If you get a message
indicating Photoshop is low on memory, purging
states is useful, since the command deletes the
states from the Undo buffer, and frees up memory.
This action cannot be undone.
