Use the excellent guide-key instead.

Let Emacs suggest you which key bindings to press.

This package will probably be most useful to new Emacs users wondering how to unleash the power under their fingerprints.

Have you ever learned all emacs key bindings ? Most likely you know some of them just to keep efficent while coding. Do you know all those shiny new bindings installed by some cool minor mode? Can you remember them all?

What if Emacs could give you suggestions on which keys to press when it notices you have entered just part of a command. For example, if you press C-x and wait for a sec you'll be shown in the echo area which keys are available under that mapping, so you'll see for example f, and just pressing f will execute the find-file command.

Install with package.el from MELPA or Marmalade

M-x package-install RET keymap-suggest RET

Or with el-get

(el-get 'sync 'keymap-suggest)

(keymap-suggest-mode)

You can set the keymap-suggest:interval variable to the number (or fraction) of seconds after which emacs should present suggestions. The default value is 1 second. Note that if you change this value you need to disable an re-enable keymap-suggest-mode
