Abstract
Letters (more generally, language symbols) are entered electronically by selecting, in sequential fashion, two keys on a standard phone layout. In preferred embodiments, the two keys in the sequence are located in the same row. The first key selected is that key on which the desired letter is displayed, and the second key is given by the spatial position of the desired letter within its group of letters on the key. The letters and keys may be color-coded to aid the user when inputting the two-key sequences. Letters may be selected to spell out words on a screen and then sent electronically to a remote device or recipient.
