binding a key to a function with an argument

binding a key to a function with an argument

[John Withers]

Folks,

I am trying to change C-x C-s save-buffer to save-some-buffers with the
non-nil argument so that it will save all without questions. 

I have no problem with the bind of the save-some-buffers:

(global-set-key (kbd "C-x C-s") 'save--some-buffers)

but I can't figure out how to pass the non-nil argument. I have tried a
few different ways and they all throw errors.

Any help would be appreciated.

The second parameter for global-set-key must be a symbol of interactive
function and you can only pass interactive prefix arguments to that
function. But you can create a new function which calls
save-some-buffers with the arguments you like. I use anonymous function
(lambda) here:

    (global-set-key (kbd "C-x C-s")
                    (lambda () (interactive)
                      (save-some-buffers t)))

how about use lambda ?

(global-set-key (kbd "C-x s") '(lambda()
				(interactive)
				(save-some-buffers t)))

an alternative way using keystrokes: C-x s !
