If I understand what you’re asking, the steps I’d use are

1. In the themes directory, copy page.php (or another appropriate template file) to, say, tpl-listings.php. Edit it and put the following code at the very top:

<?php
/*
Template Name: Listings
*/
?>

2. Edit tpl-listings.php and find the guts of the page (probably “the Loop”) and replace that with

<IFRAME SRC="http://Link to the Listing Site" TITLE="your title" frameborder=0>
<!-- Alternate content for non-supporting browsers -->
<a href="http://Link to the Listing Site">Text for the no-frames Link</a>

</IFRAME>'

3. Create a page in WordPress and associate it with the page template Listings. [See the “Page Template” drop down over on the right of the “Write Page” screen. “Listings” should be one of your choices there.] Publish the page and the external web page should show up in the WordPress context.

4. There are other attributes of the IFRAME tag (see, for instance, this site) that should allow you to fine tune the placement of the external page.

You may be thinking of something more sophisticated, but I’ve found this helpful when a simple solution was all that was needed.

What’s the code that’s generating the next/previous links? Is it using the previous_post, next_post Template Tags, or the newer posts_nav_link tag?

You can probably find that in the single.php in your theme directory. Without seeing more specifics, it’s really hard to guess what’s going on.

Yes, using “anchor” for “named anchor/bookmark” is not unusual.

Note that in the default WordPress installation, the HotKey labeled “anchor” (ALT + SHIFT + A on Windows) does insert a “link” (i.e <a href=...).

“Anchor tags” are simply the glue that makes the web work. Any link that appears on a page is, in its HTML,

<a href="the address">the text</a>

I’ll let others comment on where the “anchor” term came from (or see reference below). I think most of us simply call them “links”.

In my experience, the word “anchor” is used most often in the context of “named anchor.” Perhaps that’s what you’re asking?

“Named anchors” (aka bookmarks) can be used when you want to link directly to several places on a long page.

If the HTML on a page looks like

</h1><a name=somename></a>Major Heading</h1>

Then elsewhere on the page you can have a link (anchor) like
<a href="#somename">some link text</a>
and clicking the link will move the page so that “Major Heading” is at the top (as long as there’s a screenful of info below it on the page).

You can also link directly to that Major Heading section from *another* page with

<a href="the-page-address#somename">some link text</a>
