+  <p><c><![CDATA[tty]]></c> is a simple command line interface program where keystrokes are collected and interpreted. Completed lines are sent to the shell for interpretation. There is a simple history mechanism, which saves previous lines. These can be edited before sending them to the shell.
+    <c><![CDATA[tty]]></c> is started when Erlang is started with the command:<br></br></p>
+  <p><em>erl</em></p>
+  <p><c><![CDATA[tty]]></c> operates in one of two modes:<br></br></p>
+  <list type="bulleted">
+    <item>
+      <p><em>normal mode</em>, in which lines of text can be edited and sent to the shell.</p>
+    </item>
+    <item>
+      <p><em>shell break</em> mode, which allows the user to kill the current shell, start multiple shells etc. Shell break mode is started by typing <em>Control G</em>.</p>
+    </item>
+  </list>
+
+  <section>
+    <title>Normal Mode</title>
+    <p>In normal mode keystrokes from the user are collected and interpreted by <c><![CDATA[tty]]></c>. Most of the <em>emacs</em> line editing commands are supported. The following is a complete list of the supported line editing commands.<br></br></p>
