A useful tip, brought to you from Bob Umlas, via Mike Alexander:

If you want to display the named ranges in a spreadsheet, one way is to open the Name Manager (from the Formulas ribbon).  Another is to press F3, which also allows you to paste the list of names to the spreadsheet.  A third (and it seems little known) method is to zoom out to a scale of 39% or less.  The named ranges will then be displayed as a watermark:

Each method has its advantages, but to my mind the zoom to 39% is particularly useful because:

• It displays just the range names in the particular area of interest.
• It gives an instant visual picture of parts of the spreadsheet badly in need of a tidy up!
