Hey
I recently got Photoshop CS6, and I still have some trouble getting used to it, so I hope someone can help. I would like to know, how do I place thos cyan-light blue lines. I was wondering for a while, but never bothered to look for them. I miss them, since they're quite useful (at least for me), but I don't know how they're called, so I can't Google it :/ Anyway, as it's hard to describe it, here's a pic of a document I downloaded, that coincidentally had those lines
Hope this is detailed enough, so you guys can help.
Thanks
