Glory, glory, glory! As of tonight, the mystery is solved!
Browsing the forums here, I found the thread about "OmniFocus URL Support" located
here , and tried this script myself...
Code:
property target_URL : "omnifocus:"
open location target_URL
And, it does EXACTLY what I was looking for: using FastScripts - I now have a keyboard shortcut that launches OmniFocus, if it's not already running, or, if running, brings it to the foreground.
Now, back to our usually scheduled programming...
