You can accomplish basically the same thing using the ''code'' macro in Clearspace. Example:
puts "Hello World!"
That worked! 2 follow-up issues:
in the macro, can you make the scroll bars invisible when they are not needed instead of just disabling them?
where can I get more information on the macros supported by Clearspace? I couldn''t find anything in the documentation...
The clearspace documentation is included in the docs directory of the download and available online here: http://www.jivesoftware.com/builds/docs/clearspace/latest/index.html
If you wanted to change the behavior of the code scroll bars you can look at the css and the underling java actions
