This one is new in Eclipse 3.3 - a neat UI Element interface - it's bound to CTRL+3 so it doesn't work in the CFEclipse perspective - but you can of course change that...
Simply press CTRL+3 and a dialog will popup - you can then enter text to filter things - very neat!
The next one may have been in 3.2 but I never noticed it before - right click in the line number gutter and set a task - without using a TODO in a comment.
Click on "Add Task" gets you another dialog:
I use TODO tasks all the time in my code as little reminders - but this will allow me to do that without littering my code with comments!
Couple of other tips:
- Click the CTRL button while scrolling with the mouse wheel to jump pages
- Use the new command Ctrl+Alt+J in a text editor to join lines. Select 3-4 lines and just try it!
