Q: What is the "Saved Gestures" option in iOS7 for iPad, and how does it work?

Not helpful at all, but I probably should have been more specific. I'm trying to figure out how to use the custom gestures. Do they do anything more than just trace specific shapes on the screen? For example, can you make a gesture that will open your photos or mail app without having to back out of the app you're in? Or to close the app you're in without using multitasking?
