Underscores are not necessary, they are just a method introduces by Max to separate Moi's basic set of scripts from "added" scripts.

They amount to spelling the name of the script differently.

So if the spelling differs in the /Commands folder from the spelling in the Options/Shortcut key location, the name is not recognized.

Also I think that the .htm file must be spelled exactly the same as the .js file, (with different extension of course).
There are two names in the Commands folder, and two names in the Options/Shortcut key location.
(All 4 names spelled exactly the same, all 4 names without underscore, or all 4 names with underscore.

I think that the above statements are correct?
