I have seen this question asked a few times, and i am not sure what it is you are trying to do, but i will offer some solutions.
If you are typing hyperlinks in your summary or descriptions, they open in the same window by default. This is kind of a symptom when using FTB Editor, whether it is in this module, or another module, like the Text/HTML module. You can probably change this default behavior portal wide with a FTB configuration setting, but i cant say for sure as i use FCKEditor. FCKEditor by default adds any hyperlinks i type in to open in a new window.
Regardless of what editor you use, if you view the source while typing text in your editor, you can insert target=blank where your hyperlink is to have it open in a new window. Example, viewing the source for a DNN Hyperlink shows this ...
<A href="http://www.dotnetnuke.com">www.dotnetnuke.com</A>
but adding the target=blank like this will make that link open in a new window, like so ...
<A target=blank href="http://www.dotnetnuke.com">www.dotnetnuke.com</A>
You can use this same syntax in your template.html like this example for the download token, by changing this ...
<td width="22%">[DOWNLOAD]</td>
to this ...
<td width="22%"><A target=blank href="[DOWNLOAD]"></A></td>
In some cases, you might need to remove the " or change the " to a single ' depending on the token you are using.
The templating system can be as basic or as complex as you want by using basic html or even some javascript. Steve has given us some Tokens to use, and we can be pretty creative in using them.
As an example, i took the Nifty Toggle template and modded it a little. I didnt want to use the button in the template, but instead, made the Title clickable to Expand and Contract the View Details / Hide Details and added a Mouse Over to say "Click to view the Full Description" when you hover over the Title. You can see what i mean here ... http://www.fsalliance.net/FileLibrary/Downloads/tabid/61/Default.aspx
Anyways, take a Template, copy it and give it a new name, and experiment a little. You can do quite a bit with the templating system.
Hope that helps you.
