How does one use the Label command from the Insert Menu/Name when using Named
Ranges?

If I'm using Natural Language Formulas, i.e. using column headings as
arguments in my functions (without defining the column headings as names), is
there a way to determine what range of cells that name refers to, without
having to scroll back up to the top of the column?

Let's say I have the column heading "January" and underneath I have 5000
cells of every sale made in January. Below, I use, =SUM(January). I would
like to know what January in the SUM function refers to quickly.

Thanks.
