Neutron, I used to be able to use a keyboard shortcut without the desktop shortcut on an older computer running Windows XP, but perhaps I had created the shortcut from the start menu, the way PCAce (above) suggested. I don't remember. Anyway, thanks for the link; I'll check it out.
PCAce, thanks for your suggestions; I was able to create the shortcut from the Start menu so all is well.
Thanks so much.
