Excel

Hi Ian, thanks for your query. After some research this does not appear to be possible using standard Excel. If you've seen this in Excel it's almost certainly a bespoke add-in, or possibly an old version of Lotus! There are however, a lot of other navigational alternatives out there, for example here:

Hope this helps,
