The pattern playground feature is simply amazing :)

Any beginner who reads this message and is scared of using the regular expression / grep Find/Replace feature, make sure you read Chapter 8 "Searching with Grep" on page 177 and "Pattern Playgrounds" on page 208.

I don't have the Change Notes at hand but that's a relatively recent feature.
