Ack! I'm sorry! I started out with "pre" elements, but they were causing problems with copying and pasting (it looked odd, and it added a dreadful newline so the command would execute on paste!)
The plan is to have a pdf shortly; that will most definitely be copy and pasteable.
Small nitpick/question: why put the commands in inputs? Do you edit them on that page? Or is it just to format them?
I tried to do a copy/paste on the page contents to my personal offline notebook but the most important bits, the commands, didn't paste.
