I know there are going to be (probably already are) some out there in the BUG community new to Eclipse development, so I thought I’d post some stuff I found useful when I was first learning it. First off, short cut keys.
Also, in Eclipse shift+alt+q+h brings up a cheat sheet of the shortcuts
A lot of useful stuff can be found in Help->Java Development User Guide->Tips & Tricks
I also found just right clicking on any warnings or errors will get you familiar with the quick fix/assist easily.
One of the nice things for me is the code generation, if you right click on a class and click source (or shift+alt+s) you can get a lot of useful stuff, I use the "generate getters and setters" every time I make a class.
I have barely scratched the surface of it, but I have sped up my coding quite a bit from when I used Vi and g++. There is also an emacs mode if you want those keystrokes, go to Window->Preferences
Hope that helps a bit!
