I love this hack for hitting C-c C-c in vim and having your current paragraph telegraphed to whatever screen window you want. I imagine it'd work for demos just as well as developing bash scripts.
Very cool. I love vim and never came across this post. In fact, the link to Jerris Welt's post on 'Scripting screen for fun and profit' [1] seems handy also.
