Thanks! Wow, that will save me lots of time. Ummmm, I don't see how to "paste as node". My version of Leo has no menu item or leo command that seems to be that. Of course I can just paste it into the body of a node, but that won't give the same result.
So I opened a new text file, pasted your content in, and named the file something-or-other.leo I loaded it into Leo, and it works just as advertised, button and all. Thanks!
