<p>Whenever I indent <code>HTML</code> in <code>PHP</code> mode, <code>emacs (22.1.1, basic install on Redaht Linux over Putty-SSH)</code> pops up a frame and tells me to get <code>MUMODE</code> or <code>somesuch</code> extra add-on.  I installed <code>PHP</code> Mode without a big hassle, but I don't know how to get this multi-mode rolling.<br>
<hr>
I'd like to know 2 things</p>

<pre><code>How to install and configure multi-mode
How to disable pop-ups in Emacs
</code></pre>

If you're running emacs 22, you should just be able to run:
```
```
M-x nxhtml-mumamo
```
```
when editing an html document.  You might want to add it to your auto-mode-alist to get it to automatically load for html docs.  See here for more info:
