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) >From: Kevin Rodgers >To: help-gnu-emacs@gnu.org >Subject: Re: List possible completions in pop-up menu and choose from it. >Date: Fri, 19 Aug 2005 11:57:21 -0600 > >Rolex JM wrote: > > I want to list in pop-up menu the possible completions returned from > > (dabbrev-completion).
