O	Circle
What it does:  Opens an edit pad for a word or selection in text, fill-in fields, and labels.  Opens an edit pad for a document title; an entry in a table of contents; or a label on a tab, icon, or reference button. 

Draw:  Start the top of the circle at the top of the object you want to edit.  Draw a neatly closed counter-clockwise circle or oval.

What doesn't work:  Not starting at the top of the circle; not closing the circle; overlapping too much (a little overlap is okay).
