Based on some Twitter conversations with @fredjean about the Codex Ruby Gem, I've been inspired to stop taking screenshots of code for slides and rather putting in formatted text. But this isn't as easy to do as it should be. Eclipse 3.4 has lost (for me, and others) the ability to copy and paste rich text so that it appears formatted in the paste destination. Maybe that's a MacOS failure of later Eclipse versions. No matter though, as I drift father from Eclipse usage. My favorite other two editors can fulfill this need nicely with two simple add-ons.
