The most users know and are experienced with the GSM standard keypad and enter the text automatically without thinking where is a given key. In devices with lateral keys this experience is lost and the process of entering the text is slowed down. In addition the lateral placement of the keys requires visually coordinated either bi-manual operation or a larger distance to move the finger for one-handed operation. The core of the invention is an alignment of a virtual keyboard with the lateral keys on one side of the phone. The access to all the characters of the virtual keyboard is based on using jointly the navikey/joystick and the lateral numerical keys.
