how to make dabbrev expand to 2nd/3rd/... last occurence?

how to make dabbrev expand to 2nd/3rd/... last occurence?

[Florian Kaufmann]

Hello

Is there an extension to the dabbrev mode so that I can also have
´printed´ the 2nd/3rd... last occurence of a word? For example
something like this. Say I have dabbrev-expand bound to C-; .Pressing
C-; would behave normaly, another ; would replace the just found
occurence with the 2nd last occurence, another ; would replace it with
the 3rd last occurence and so on. 

Greetings

I have to add that I know that there is also dabbrev-completion.
However this is not as convininient as just press C-; and then some ;
until I have the right one.

I'd use C-; again, since you have C- already pressed.

Otherwise you have to modify the behavior of ";"


Something like 

(defun my-semi-or-complete (&optional arg)
  (interactive "p")        
  (let ((n (if arg         
               arg         
             1)))          
     (if (or (eq last-command 'my-semi-or-complete) (eq last-command 'dabbrev-expand))   
         (call-interactively 'dabbrev-expand)
      (insert-char ?\; n))))


which can be bound to ";"

(global-set-key (kbd ";") 'my-semi-or-complete)


(Probably not the best solution.)

Thank you Holger

Tststs, I'm sorry to have asked a question that is so obviously in the
help. I actually read the help before I posted my question, but
obviously very carelessly.
