In one embodiment, a user interface is presented for initiating activities in an electronic device. The user interface includes an element referred to as a “launch wave”, which can be activated at substantially any time, even if the user is engaged with an activity, without requiring the user to first return to a home screen. In various embodiments, the user can activate the launch wave by performing a gesture, or by pressing a physical button, or by tapping at a particular location on a touchscreen, or by activating a keyboard command. In one embodiment, activation of the launch wave and selection of an item from the launch wave can be performed in one continuous operation on a touch-sensitive screen, so as to improve the expediency and convenience of launching applications and other items.
