<p>This is the stuff I use every day:</p>
<ul class="simple">
<li>command line recall:<ul>
<li>hit the “up arrow” key</li>
<li>if you have typed a bit, it will find the last command that starts the same way.</li>
</ul>
</li>
<li>basic shell commands:<ul>
<li><code class="docutils literal"><span class="pre">ls</span></code>, <code class="docutils literal"><span class="pre">cd</span></code>, <code class="docutils literal"><span class="pre">pwd</span></code></li>
</ul>
</li>
<li>any shell command:</li>
</ul>
<blockquote>

<li><code class="docutils literal"><span class="pre">!</span> <span class="pre">the_shell_command</span></code></li>
</ul>

<ul class="simple">
<li>pasting from the clipboard:<ul>
<li><code class="docutils literal"><span class="pre">%paste</span></code> (this keeps whitespace cleaner for you)</li>
</ul>
</li>
</ul>
<ul class="simple">
