Eclipse Shortcuts
#1

Editors are an integral part of a programmer?s life. If you have good proficiency in using an editor thats a great advantage. It comes very handy to debug. Traditional notepad and SOPs (System.out.println) are the way we start learning a language but that is not sufficient, so beginners start using an IDE and most importantly know the shortcuts.
For java developers there is a huge list and some popular areEclipse, Netbeans, IntelliJ Idea. I use Eclipse as my IDE and vim as a light weight editor.

This article is for those who use or intend to use Eclipse as IDE. Keyboard shortcuts are very important for comfortable and quick editing. I have abridged the following list of eclipse shortcuts from my own experience and literature.
