               // and mouse events, and similar.
               //
               // Specific autocompleters need to provide, at the very least,
               // a getUpdatedChoices function that will be invoked every time
               // the text inside the monitored textbox changes. This method

               // autocompletion. Specific auto-completion logic (AJAX, etc)
               // belongs in getUpdatedChoices.
               //
               // Tokenized incremental autocompletion is enabled automatically
               // when an autocompleter is instantiated with the 'tokens' option
               // in the options parameter, e.g.:
               // new Ajax.Autocompleter('id','upd', '/url/', { tokens: ',' });
               // will incrementally autocomplete with a comma as the token.
               // Additionally, ',' in the above example can be replaced with
               // a token array, e.g. { tokens: [',', '\n'] } which
               // enables autocompletion on multiple tokens. This is most
               // useful when one of the tokens is \n (a newline), as it
               // allows smart autocompletion after linebreaks.
