My favorite CodeRush/Refactor! Pro features

1. Ctrl+3 aka embed method in region with the name of method
2. Auto Completition aka completes the word you are typing and mostly the suggestion is correct.
3. Introduce local aka extracts an expression and assign it to a variable.
4. Templates aka CR writes code blocks for you.
5. Moving within an identifier aka jumping between different casing instead of whole word.

And these are only most used features right out my head. There are tons of other excellent features worth exploring.
