Eclipse is my favorite tool since I started coding in Java. Over past few years I have learned many shortcuts and these Shortcuts have made my life very easy and highly productive. Eclipse supports a huge number of shortcuts, however not all of them are useful in everyday programming life.
This article is listing down the really useful shortcuts that are quick to learn and use. You will also start remembering them since these are often required in every day development tasks.
Developer and programmers are typically keyboard friendly and they like to do as many things as possible with keyboard shortcuts.
Many shortcuts that work on Windows system are also applicable inside the eclipse IDE and I am sure you must be using them already. My favorite one is Copy (CTRL + C) and Paste (CTRL + V)
