In the four corners of my blank word document, there are four gray colored,
"L" shaped markers. They line up with the margin indicators and move left and
right when I move the margin markers. they appear to indicate where text will
appear on the page while I type.

These marks appeared one day when i accidentally hit some keys on my
keyboard. I cannot find the name for these marks or how to toggle them on and
off.

Can someone tell me the keyboard shortcut to turn them off and, as an aside,
what they are called?

thanks
