> There is also an argument to be made that EMACS was not an improvement over TECO. Full disclosure: I've been using emacs since 1981. ISTR TECO under TOPS was a PITA. eg. From Sec 4-1 Some characters, like <CTRL/U>, are both regular TECO commands and immediate action commands. The command string ^Uqtext` enters the specified text into Q-register q. However, <CTRL/U> typed while entering a command string is an immediate action editing character which deletes the current line. Thus you cannot type a <CTRL/U> (or any similar sequence) directly into TECO as part of a command string. Nevertheless, <CTRL/U> is still a valid TECO command; should TECO encounter it in a macro or indirect file, it will have its regular TECO effect (^Uqtext`). http://h71000.www7.hp.com/doc/73final/documentation/pdf/teco.pdf http://h71000.www7.hp.com/doc/73final/documentation/pdf/teco...
