Abstract: A process and apparatus for entering a predetermined number of characters use an entry terminal having a display and a keyboard having a predetermined number of character entry keys presented in a first array (ten key numeric keyboard) and a predetermined number of function keys, with the predetermined number of character entry keys being fewer in number than the predetermined number of characters. The process comprises the steps of presenting on the display more than one cluster of characters to be selected, with each cluster containing fewer than the predetermined number of characters, and with each cluster of characters being presented on the display in a second array; selecting, via a function key, one of the clusters of characters which contains the character to be entered via the terminal; and actuating one of the character entry keys whose position in the first array bears a predetermined relationship with the position in the second array held by the character to be entered.
