Well this tip is not from my head (thanks Gregg ;-)... You can navigate very fast to a method in source editor by following these steps:
1. Press Ctrl-7 to get focus to navigator.
2. Type in first letters of the method, e.g. "ma" for main.
3. Press enter -> now you are moved to the beginning of the method.
A nice small time saver - you don't need to use the mouse to scroll down or search for the method or field.
