What's hidden?

I have a spread*** with a dozen wide columns.
I have occassion to hide columns so I can fit what I want to see on a
screen. However, sometimes I need to see a hidden column and I don't
recall which one it was. I don't want to have to unhide everything so
I can locate that column.
Is there a trick to seeing the column headings without having to
unhide them? or is there an easy toggle between hide and unhide? -
