I'm not a fan of <? and ?> really as it doesn't validate on the w3 web site
validator thing :-)

It is a bit annoying, I'm playing about with PHP myself.

You are missing something, just keep typing and your text will be entered,
or press space again and a space will be inserted, although this depends
on the mouse not being over a menu item.

I'll sort out the escape key thing.  It may also be an idea to check if
the cursor is in an entity.

thats a good idea, as you say html may be wanted in a script.

well thats what I initially meant.

So the cases that need to be handled are:

<script>
<? ?>
<% %>
<!-- -->
 
any others?

I've no idea what they could be used for either, but I'm sure there is
a use somewhere.
