"?": A Context-Sensitive Help System Based on Hypertext

Commercial on-line help systems are still largely text-based using TTY interfaces, even on bitmap graphics workstations. Context-sensitive help for on-screen objects on workstations is one important feature lacking in today's help systems. This paper describes a new system called "?"(FOOTNOTE: "?" is pronounced "eh?"; "eh" is derived from err_help which is described in the implementation section.) based on hyper-text which mixes text, graphics and movies and allows the user to peruse the entire help database through the use of reference buttons.
