InDesign expert and CreativePro.com author Michael Murphy recently recorded the course "InDesign CS4: Learning GREP" for lynda.com.

GREP may sound like a noise you'd make after eating a large meal, but it's actually one of your most powerful weapons against repetitive InDesign tasks.

Think of GREP (which stands for General Regular Expression Parser) as a really smart, really powerful Find/Change. With this course under your belt, you can search for and replace all sorts of formatting in InDesign files.

Exercise files come with the course, which is 3 hours and 45 minutes long. If you're the sort who won't buy until you try, you can listen to the following segments for free:

- What is GREP?
- Text searching vs. GREP searching
- Working with GREP and InDesign
- Using metacharacters, the building blocks of GREP
- Escaping out metacharacters
- Building with wild cards
- Understanding undocumented wild card "opposites"
- Specifying exact matches and ranges
