A while ago I posted about some shortcuts I often use in Eclipse. Well this morning I found a new shortcut that I can't believe I never knew about; and while borderline, I deemed it worthy of it's own post!

ALT + UP-ARROW
ALT + DOWN-ARROW

I tend to be an ordering freak and this little gem of simplicity is way better than cutting and pasting. This short-cut key will move any line your cursor is on or any lines you have selected in the direction you press.
