I'm used to applications allowing you to perform multiple undos at once with Ctrl-Z. I've found that at least the default setting in photoshop is only a single undo. How do i change this (im a photoshop newbie)?
In Photoshop CS3 you go Edit->Keyboard Shortcuts
Here you can change/add keyboard shortcuts to most Photoshop menu items, palette menus and tools.
Simply choose the Edit accordion section and click on the Step Backwards shortcut and click Ctrl-Z.
It might throw a warning as it is will be overwriting the Undo/Redo button, but don't worry about that.
Now you have it set up the way it should be.
Thanks S.Kiers! I am using a Wacom tablet and have found that I can spend a lot of time drawing without touching the keyboard, as I have mapped space bar (hand tool) and undo to my two stylus keys.. however, I have been leaning over to the keyboard every time I want to bo back more than 1 step.. now I can finally sort this! Hooray!
