Need to toss a bunch of items in a folder really fast? Mac OS X has a nifty shortcut that manages the operation in one fell swoop so you don't have to make a folder and then take further action to populate it.
Just select the items you want in the Finder, right-click (or two-finger tap) on them to bring up OS X's contextual menu, and choose the first option: New Folder with Selection. The Finder will then create a new folder with those items stored safely inside, removing at least one step from the process for you automatically. Super easy!
