Abstract

Methods and devices provide an efficient user interface for activating a function by detecting a tickle gesture on a touch surface of a computing device. The tickle gesture may include short strokes in approximately opposite directions traced on a touch surface, such as a touchscreen or touchpad. The activated function may open an application or activate a search function. The index menu item may change based on the location and/or movement of the touch on the touch surface. Such functionality may show search results based on the menu item displayed before the user'"'"'s finger was lifted from the touch surface.
