Abstract: A method for selecting at least one element of a Graphical User Interface (GUI), displayed on a display of a device using a touch interface of the device. The method includes: detecting on the touch interface a double touch input, the double touch input including a first and second touch inputs on the touch interface, the first and second touch inputs respectively corresponding to a first location and a second location on the GUI; determining a selection location between the first and second locations; upon detecting a release of the first touch input, determining a first selection location corresponding to the selection location at the moment of the release of the first touch input, determining a second selection location on the GUI as defined by a user using the touch interface; and executing a selection of at least one GUI element located between the first and second selection locations.
