 <h2 class="chapter">Keymaps</h2>  <p>The command bindings of input events are recorded in data structures called <em>keymaps</em>. Each entry in a keymap associates (or <em>binds</em>) an individual event type, either to another keymap or to a command. When an event type is bound to a keymap, that keymap is used to look up the next input event; this continues until a command is found. The whole process is called <em>key lookup</em>. </p> <table class="menu" border="0" cellspacing="0"> <tr>
