Re: List possible completions in pop-up menu and choose from it.

["Jimmy Rolex" <rolexletter@hotmail.com>]

Thank you for your help.

Now I add following code to my site-start.el. When I press [M-up], the menu 

appears at point, with possible completions inside. It looks good.

However, after I select one item inside with mouse or keyboard, the 
selection
isn't inserted into the buffer. Have I done something wrong?

(defun my-dabbrev-completion ()
  "*Just like `dabbrev-completion', but display a popup menu."
  (interactive)
  (save-window-excursion               ; suppress *Completions* buffer
    (dabbrev-completion))
  (let ((menu (make-sparse-keymap "dabbrev-completion"))
        (completions (let ((symbols '()))
                       (mapatoms (lambda (sym)
                                   (setq symbols (cons sym symbols)))
                                 dabbrev--last-obarray)
                       (sort symbols 'string-lessp))))
    (mapc (lambda (completion)
            (define-key menu (vector completion)
              `(,(symbol-name completion) .
                (lambda ()
                  (interactive)
                  (insert ,(symbol-name completion))))))
          (nreverse completions))
    (autoload 'senator-completion-menu-point-as-event "senator" "" t)
    (x-popup-menu (senator-completion-menu-point-as-event) menu));;pop-up 
at point
  )

(global-set-key [M-up] 'my-dabbrev-completion)
