There is a check box in the fields area (once you add a field) which opens up the doors for a ton of cool features without having to code tpl files etc.
You can see a sample image at http://www.rivervalleytechcollective.org/files/thebutton.png
Once you click this a field appears under it where you can enter html and token like fields.
The tokens happen by adding field above it. Any fields above it can be called to in this field. You can then set those fields to exclude from view to have them not show up twice.
Here is an example code.
<a href=/node/[nid] class=cluetip title='[title]|[body]'>[title]</a>
So here I am calling to the NID field and the BODY field above.
Cause I loaded the http://drupal.org/project/cluetip module I then joined the two fields in the title area so you get a pop up bubble when you hover over the URL.
Simple but a nice feature.
Then next trick will be http://drupal.org/project/popups module and editfield module.
