Some of you may know about @rtrouton's post about a hidden property sheet in the Script Editor. Have a look-see, because it absolutely relates to what I'm about to tell you:
I discovered a cool easter egg in the Script Editor that makes moving text around very, very easy.
First, put your cursor on any line of text. Now hold the alt/option key and use the up or down arrows and watch as that line of text moves up or down.
Next, try selecting multiple lines of your script. Now try alt-up or alt-down and see how the block of text moves together in the editing area. Pretty neat, huh?
Neat, huh?
