Abstract

Disclosed are a mobile terminal and a multitasking method thereof. In a state where a plurality of layers corresponding to a plurality of applications are displayed on a screen, a user performs an operation through an uppermost application. In this case, a search region of a preset shape through which a lower application can be directly visible is created on the uppermost application. This can allow the user to more rapidly and conveniently search for or select information provided from the lower application, and to apply the information to multitasking.
