Thanks for that tip, @ccstone.
With Script Debugger it's amazing what's provided for free. Even though I'm far from a power user, it just seemed right to purchase a v8 license. So I did.
Yes, the information quantity is much greater and the organization is impeccable.
I'll be nice when I ask. 
On a related note...
When I was recently using Script Debugger and scripting the Keyboard Maestro editor, I encountered an issue that maybe you or others on this forum have encountered: with File > Open Dictionary > Keyboard Maestro and using the Explorer tab, it starts up as expected by after a few minutes of use indicates Application Not Running. Sometimes I subsequently see a dialog to Launch Keyboard Maestro (even though it is open) but that never seems to have any effect. However, if I manually Quit are reopen KM, the SD Explorer tab seems to normally, but not always, reconnect.
@ccstone (or anyone else), have you seen this issue? (Maybe another topic for the SD forum.)
