title: emacs error: Key sequence M-x g starts with non-prefix key M-x
body: <p>I have the following code in <code>.emacs</code>: <code>(global-set-key (kbd "M-x g") 'gnus)</code> to start Gnus with the keybinding <code>M-x g</code>. I obtain: <code>error: Key sequence M-x g starts with non-prefix key M-x</code>. How can I define keybindings starting with <code>M-x</code>? Is this a bad thing to do and should be avoided? I find it more intuitive since the "long version" is <code>M-x gnus</code>. Defining it as <code>C-c g</code> for example is no problem but then you start Gnus with <code>C-c g</code> and, for example, R via <code>M-x R</code> which is not very intuitive (in contrast to starting both via <code>M-x + 1 letter</code> </p>
