Trap forward/back mouse buttons
 

Does anyone know how to trap the forward/back click buttons normally
used in conjunction with a web browser? I guess this requires an API
call but haven't been able to find any clues.

I have written a short piece of code which tracks my cell selections
and allows me to retrace my steps, eg. to help when debugging
formulas. It would be neat to be able to tie this back to the mouse
buttons for really simple use.

Thanks a lot,
Andrew
