I was just working with the pen tool in Photoshop CS6, and unexplainably the anchor points changed from being circles to being squares. I have no idea how I did it or how to reverse it. What with all the keyboard shortcuts it's possible that I accidentally hit the keystrokes to change it (as I have done it in the past), however I have been unable to find exactly why or how I made this change.
Your help would be greatly appreciated!

Not only do they look square, but they're a little bigger than usual.
I've never run across any option that changes the way path controls are shown. What version of Photoshop do you have?
If no one identifies a configuration option I've never seen there are, of course, the old fallbacks: Reset the Path tool, restart Photoshop, reboot the system, or clear all Photoshop preferences to defaults.
Shortly after I did in fact restart and thankfully the problem fixed itself. I am curious still what key combination is assigned to do such a change, as I have not seen anyone else with this preference, or a keyboard shortcut on the help pages.
