"Step Backward" in Photoshop CS6

[JoeJ]

How to increase the number of times that "Step Backward" can be used when editing a photo in Photoshop CS6? Is it enough to enter the desired number in "History States"?

Thank you in advance for your help.

Preferences, performance, and then history states.

Just be careful about setting it to high as this tends to use up more RAM
