I remember there was a simple way to put a sentence or two into the "function
arguments" box that comes up when you click fx while typing a public function
in Excel. There was something you could right-click and it doesn't show up
in the code. Does anyone remember how to do that?

For example, if you type =sumif( into a cell and then click the fx button,
you can see "Adds cells specified by a given condition or criteria". There's
a way to update that info.

Thanks.
