A universal display keyboard can include a plurality of keys whose identifying indicia can be altered via electronically-alterable displays associated with the keys. In one embodiment, indicia associated with character and function keys can be controlled by the currently active application of an electronic device external to the keyboard. The keyboard can also include a plurality of user-operable mode-changing keys or elements to select state changes for the plurality of character and function keys. The keyboard can optionally include one or more built-in display windows to show the user helpful information about the keys or to provide application menu information. Various methods, as well as application of the keyboard to a keyboard system and to a data processing system, are also described.
