Change the frame width in Emacs, Interactively

I know you can change the frame size in the .emacs file with set-frame-width or (add-to-list 'default-frame-alist '(width . 80)) but how can I change the width after Emacs has started up (aside from dragging the edge of the frame)?

To toggle between 2 frame sizes easily you could define something like that (e.g., add it to your ".emacs" file) (adapt the sizes to your screen and fonts)

     (defvar myfullscreen '()
       "non-nil if current frame is in fullscreen mode. See myfullscreen-on, myfullscreen-off, myfullscreen-toggle")

     (defun myfullscreen-on ()
       "Sets fullscreen on (based on ???display??? with font ???)"
       (interactive)
       (set-frame-width (selected-frame) 177); adapt size
       (set-frame-height (selected-frame) 58); adapt size
       (setq myfullscreen t)
       )

     (defun myfullscreen-off ()
       "Sets fullscreen off (based on ???display??? with font ???)"  
       (interactive)
       (set-frame-width (selected-frame) 110); adapt size
       (set-frame-height (selected-frame) 58); adapt size
       (setq myfullscreen nil)
       )

     (defun myfullscreen-toggle ()
       "Toggles fullscreen on/off (based on ???Display??? with font ???)"    
       (interactive)
       (if (eq myfullscreen 'nil)
           (myfullscreen-on)
                                    ;else
         (myfullscreen-off)
         )
       )

Then, you can use

M-x myfullscreen-on

M-x myfullscreen-off

M-x myfullscreen-toggle

and/or bind them to your favorite key bindings

This library has a bunch of interactive commands for your use: http://www.emacswiki.org/emacs/frame-cmds.el

Here are a few relevant ones:

enlarge-frame

hide-frame
mouse-show-hide-mark-unmark
move-frame-down

In addition to Charlie Martin's suggestions, you can do

M-: (set-frame-width (selected-frame) N)

Well, go to the *scratch* buffer and use set-frame-width.

(set-frame-width (selected-frame) 100)  ;; ^J to execute.

set-frame-width isn't interactive, so you can't run it with M-x but you could trivially write a set-frame-width-interactive, something like

(defun set-frame-width-interactive (arg)
   (interactive "p")
   (set-frame-width (selected-frame) arg))

Now C-u 8 0 M-x set-frame-width-interactive will set the width to 80.

Is this what you're trying to do?
