A day late and prob'ly a dollar short, but I thought I'd throw my 2cents in...
You can also find "Clip Basics" in the index of the NoteTab Help file (the
first Help file listed under the Help menu). This is not listed in the Clip
Script Help File index, but you do find it mentioned and will link back to
the NoteTab help file in both the Custom Functions & Clip Wizard and Fields
sections of the Clip Script Help File. I have it referenced under Favorites
in the Clip Script Help file for quick access to it upon occasion. (As an
aside, I also have the Regular Expressions topic bookmarked in Favorites in
the Clip Help for easy access.)
The Clip Basics topic should probably be in both places, but somehow got
lost in the shuffle when the Clip language got its own help file :-).
