[Pharo-project] syntax highlighting - how?

Sorry to ask such a basic question, but how do I enable syntax highlighting in Pharo? I updated to the 4.0-closure vm (on a Mac) two weeks ago. Shout is not in the package list in Monticello, so do I need to add some repository? I have searched the preferences on words like color, syntax, highlight, and variations, and I struck out. And when I have a question like this, what is the best place to look for the answer? Many squeak specific notes (historical postings) do not seem to always apply to Pharo. 4.0 seems to be working great! thanks in advance, Cam S
