Herb,

Publisher web pages are basically static fixed pages. As I see it, the
insert html code fragment tool is handy for adding some dynamic features
that are not directly supported by Publisher. Just one example would be
javascript slide shows, or perhaps a video player. You can Google for all
kinds of free script where you just insert the code snippets provided into
the Publisher page. Then when you Publish to the Web and produce the html
code...the web pages, Publisher will write that code into the web pages at
the same time it converts the rest of the page to html. It is not intended
as a tool to edit the code that is produced by Publisher...it just adds to
it. That means you can't use it to edit normal hyperlinks to open in a new
window. However, you can use it to create hyperlinks that will open in a new
window.

Reference:

describes two methods. I found it easier to use the html method at first,
but eventually found the ECMAScript code approach more versatile, especially
if I had more than one hyperlink on a page that I wanted to open in a new
window.

If you choose to use the ECMAScript code approach note that the first
javascript code snippet under step 2 is incorrect on the website. Use this
instead:

<script language="JavaScript" type="text/javascript">function Show(Url,
Name, Features) { window.open(Url, Name, Features); }</script>

Just copy and paste the code snippet into a code fragment box, and then put
that box somewhere on the page where it is out of the way. It will not
appear when you actually do a web page preview.

Then when I am ready to write the hyperlink code snippet that will open in a
new window, I create a separate text box that I drag off into the scratch
area just for that purpose. I find it easier to write the links there and
then just copy and paste in the hyperlink address field when I am ready to
insert the hyperlink. You can use Ctrl + V to paste. Once you get the script
for one link to work correctly, then you have a "template" in that text box
that you can just change the URL.

I also generally use a link that does not put any limiting features on the
new window. Here is a sample:

javascript:Show('http://www.google.com/','newwindow','')

Just modify the URL of the site you want to open in a new window where it
says "google.com", copy the modified script, and paste it into the address
field of the hyperlink dialog.
