Re-open *scratch* buffer in Emacs?

Question

If I accidentally closed the scratch buffer in Emacs, how do I create a new scratch buffer?

Answer 1

(global-set-key (kbd "C-x M-z")
                '(lambda ()
                   (interactive)
                   (switch-to-buffer "*scratch*")))

This will not only quickly switch to *scratch* buffer(since I do this frequently), but recreate a *scratch* buffer and enable lisp-interaction-mode automatically if you kill it accidentally. Change the binding as you like.
