Emacs elscreen - how do I jump to numbered tabs

Elscreen has a method called elscreen-jump and also elscreen-jump-0 and elscreen-jump-9. I'd开发者_如何转开发 like to be able to jump to tabs between 0 and 9. How do I define a keymap for this? I've tried:

(global-set-key (kbd "M-1") (lambda () (interactive) (elscreen-jump 0)))
(global-set-key (kbd "M-2") (lambda () (interactive) (elscreen-jump 1)))

but I get an error:

Wrong number of arguments: (lambda nil "Switch to specified screen." (interactive) (let ((next-screen (string-to-number (string last-command-char)))) (if (and (<= 0 next-screen) (<= next-screen 9)) (elscreen-goto next-screen)))), 1

Any ideas?

It appears as if elscreen-jump doesn't take any arguments, try using the (elscreen-goto 3) instead.

I believe that is just your elscreen-prefix-key + 0, 1, 2, ... By default, the prefix key is C-z (so for instance, C-z 0). You can customize this variable, but if you set it to "M" that'll change a whole lot of things. The key bindings are in elscreen.el
