PHPStorm has been my IDE of choice for some time now. That said, there are still new shortcuts I'm either learning or implementing into my workflow all the time.
Here are some of my favorites:
- Intention Actions - creates new code items: classes, methods, parameters, etc. Fix typos, merge statements, etc..
- Search Everywhere - Search your code, databases, ide actions, user interface, etc, all from a single menu.
- Code Completion - complete the names of classes, methods, and keywords.
- Refactoring Source Code - Find and update the affected code references automatically.
