Desktop Icons, & Inner Marks In Icon

[Robert11]

Hello,

New 2007 Office user.

I see that some of the saved work icons that appear on my desktop for saved
Excel, Word, etc., have small
exclamation marks (I know that this means a macro) in it.

Is there a list somewhhere of all of these small inner-icon marks that
Office uses for saved work ?

Thanks,
B.
