The aim of the invention is to provide a device and a method for selecting text from an electronic memory using a numeric telephone keypad. To this end, a digital telephone keypad has at least one pressure sensor sensing the pressure exerted on one or more keys, control electronics processing an input via key confirmation and a text display. The pressure exerted on the keys of the digital telephone keypad is detected and measured for every key by a pressure sensor. The respective pressure value is transmitted to and processed by control electronics. The measured pressure value is shown on a display for every key. The pressure value exerted is changed for the key pressed, if necessary, and once the correct pressure value is reached and shown on the display, the pressure value for every pressed key and information on the selected key are transmitted for further processing of the measured values.
