viper: Abbreviation Facilities

 
 2.7 Abbreviation Facilities
 ===========================
 
 It is possible in Emacs to define abbrevs based on the contents of the
 buffer.  Sophisticated templates can be defined using the Emacs
 abbreviation facilities.  Abbreviations (emacs)Abbrevs, for
 details.
 
    Emacs also provides Dynamic Abbreviations.  Given a partial word,
 Emacs will search the buffer to find an extension for this word.  For
 instance, one can type ‘Abbreviations’ by typing ‘A’, followed by a
 keystroke that completed the ‘A’ to ‘Abbreviations’.  Repeated typing
 will search further back in the buffer, so that one could get ‘Abbrevs’
 by repeating the keystroke, which appears earlier in the text.  Emacs
 binds this to ‘<ESC> /’, so you will have to find a key and bind the
 function ‘dabbrev-expand’ to that key.  Facilities like this make Vi’s
 ‘:ab’ command obsolete.
