photoshop help please?!

This is driving me crazy! lol, I use cs2... I was finishing up a lo, and I went to hit ctrl + so I could zoon in a bit on my text. I didnt' have my keyboard pulled out from under my desk, just put my hands under, and thought I was hitting the right keys without looking... Apparently not. I don't know what I hit with the ctrl button, but it put this annoying grid up on my lo. It's not there when I save the jpg, but I saved the psd, and it's still there. It's also there whenever I open a new file too. Does anybody have any clue how to get it off? Here's a screen shot of what it looks like. I didn't wanna just keep hitting buttons in case I did something else I couldn't undo. Nothing popped up in my history box that I could undo either.

It looks like the Grid Presets in on. I don't know the shortcut but if you go under view you can turn them off!!!

It might also just be the "Grids" that are on, you can turn those off under view too!! If they are "ON" there will be a "check mark" next to the name!!!

LOL, It was under view > extras... the shortcut for it is cntrl h. I was just a little off on my keys there, huh? Thanks, I had no clue where to even look for that!! Learn something new every day
