The mobile device displays a scrollable communication-related list that includes but is not limited to a call log list, a message list, a phonebook list, and an email list. When a specific item is selected in response to a first touch event, the mobile device determines whether or not a second touch event occurs on the selected item in a non-scrollable direction. Then the mobile device executes a particular function predefined in the selected item in response to the second touch event occurring in the non-scrollable direction. ## Claims ### Claim 1 An apparatus comprising: memory to store a specified application;
