ido: Activation

 
 1.1 Activation
 ==============
 
 This package is distributed with Emacs, so there is no need to install
 any additional files in order to start using it.  To activate, use ‘M-x
 ido-mode’.
 
 You may wish to add the following expressions to your initialization
 file (SeeThe Emacs Initialization File (emacs)Init File.), if you
 make frequent use of features from this package.
 
      (require 'ido)
      (ido-mode t)
