Reversing Colors in Photoshop CS3

[ribbonthecat]

I have a picture that I was looking at, and then I hit ctrl-option- -8, and I like the reversed colors in the image much more. Is there a way I can do that to the image in photoshop?

In Photoshop CS2 (and CS3?) it's + i, I believe.

Invert is also an adjustment layer now as well


OT - But anyone having trouble with snapping guides in CS3? {snap is set and rulers visible}
