>Check Webster's. We call it a 'caret'. We normally refer to > as the "greater than" sign, and < as the "less than" sign, but yes, I know ^ can also be referred to as a 'circumflex'. Here it's just waaaaaay more common to call it a 'caret'. I suppose it also depends on the use. A circumflex is used to clarify pronunciation or accent, or whatever. A caret is used to show an insert.

Well, as you seemed so sure I eventually did check and got:

"a wedge-shaped mark made on written or printed matter to indicate the place where something is to be inserted"

How that is intrerpreted as being "an up-pointing arrow that goes on top of a letter to denote a different pronunciation, or where, say, in French, the "e" was formerly followed by an "s" (e.g. fenêtre cf fenestre)" I don't know.

Trust me, a caret is "greater than" or "less than" symbol. But as long as the "we" in your office are all on the same page about the meaning I suppose no harm's done :-)
