73
74<p>Although the Readline library comes with a set of Emacs-like
75keybindings installed by default, it is possible to use a different set
76of keybindings.
77Any user can customize programs that use Readline by putting
78commands in an <em>inputrc</em> file, conventionally in his home directory.
79The name of this
80file is taken from the value of the environment variable <code>INPUTRC</code>.  If
81that variable is unset, the default is <samp>~/.inputrc</samp>.  If that
82file does not exist or cannot be read, the ultimate default is
83<samp>/etc/inputrc</samp>.
84</p>
85<p>When a program which uses the Readline library starts up, the
86init file is read, and the key bindings are set.
87</p>
88<p>In addition, the <code>C-x C-r</code> command re-reads this init file, thus
89incorporating any changes that you might have made to it.
