Eclipse also offers column selection functionality similar to popular text editors Notepad++, Sublime Text2.

On a Mac, need to press "cmd + option + A"
On Windows and Linux, you need to press "alt + shift + A"

Please note doing above will take you to block selection mode, and you need to press same keys again to come back to normal mode.
