This invention relates to a method for selecting function execution by key entering data at a stored program-controlled interactive man- machine interface. The interface includes an input device having function and alphanumeric coded keys, a display, and a program element responsive to input device actuations by providing both program- originated and echo key data on the display. The method steps include (a) inputting at least a portion of the function name, (b) comparison matching visually the keyed-in name echo with a predetermined number of function names on a circular list projected on the display, the list being rotatable in either direction by function key actuation, and (c) upon a match, invoking the function. Each input is followed by a single input field.
