Hello RWSmith,
O.K., I think I have found the final piece of your puzzle.
I found a program that will enable you to assign a hot-key to your scripts 🙂
It's called FastScripts:
http://www.red-sweater.com/fastscripts/index.html
They have a full version and a "Lite" version. So, you might see if the free "Lite" version will do what you want. If not, go for the full version.
With this program, and the scripts you've already been provided, I think you might have a complete solution 🙂
I hope this helps.
P.S., feel free to mark any of the posts in this thread "helpful"
and / or "solved" if you found them useful 🙂
Anyway, I hope this gets your system exactly as you want it. Let me know.
