A method of controlling a portable electronic device that has a touch screen display moveable relative to a base thereof. The method includes rendering a graphical user interface including selectable text, detecting a touch event on the touch screen display, detecting actuation of a switch caused by movement of the touch screen display relative to the base during the touch event and determining a first location of touch at the time of actuation, detecting release of the switch and determining a second location of touch at the time of release of the switch, and selecting text from the first location of touch to the second location of touch.
