Looking at the Work Area
States are added from the top down. That is, the 
oldest state is at the top of the list, the most recent 
one at the bottom.
Each state is listed with the name of the tool or 
command used to change the image.
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. 
Selecting a state and then changing the image 
eliminates all states that come after. Likewise, 
deleting a state deletes that state and those that 
came after it.
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. 
Using the History palette
You can use the History palette to revert to a 
previous state of an image and delete an image’s 
states.
A. History state B. History state slider
C. Trash button
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.
Click the Step Forward or Step Backward 
buttons from the shortcuts bar.
Choose Step Forward or Step Backward from 
the palette menu or the Edit menu to move to the 
next or previous state.
To set the keyboard command for Step Forward 
and Step Backward, choose Edit > 
Preferences > General, and select an option for Step 
Back/Fwd. 
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 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 
Elements.
