According to TUAW, when Launchpad is displayed, a user can click and hold the mouse cursor on an app’s icon; after a brief pause, all the app icons will begin jiggling. An X will appear in the upper left-hand corner of the icons, and clicking it will cause a dialog pop-up to appear asking the user, "Are you sure you want to delete the application?" Clicking Delete will move the app and any associated files to the Trash.
