I modified my Main Index template to add code "donated" by David Gagne that adds a hidden "Edit This" link for each entry. In my case, I decided to make the hidden link that vertical bar "|" in the "Posted by" section (at bottom) of each entry.

Here's David's beautiful explanation:

	<MTEntryIfAllowComments>

<!-- Start addition -->
<a target="_blank" title="admin" onmouseover="window.status=
'edit this entry'; return true;" onmouseout="window.status=' '; 
return true;" href="<$MTCGIPath$>mt.cgi?__mode=
view&_type=entry&id=<$MTEntryID$>&blog_id=<$MTBlogID$>">|</a>
<!-- End addition -->

	 <a href="<$MTCGIPath$>mt-comments.cgi?entry_id=
<$MTEntryID$>" onclick="OpenComments(this.href); return false">
Comments (<$MTEntryCommentCount$>)</a>	
</MTEntryIfAllowComments>
