Geek Stuff: Blogger - view/filter multiple labels at one time

This post has been updated with Blogger - How to search multiple labels at one time UPDATED.

You know you can click on a label and view all the posts with that label, but you want to select multiple labels and view the posts that have all those labels. Here's how you do that.
Lets say you want to display all post entries on this blog that have the labels "Blog" and "HTML".
The URL will be this:

http://geekstuff.allnewadventures.com/search/label/Blog/label/HTML

Or simply

http://BLOG-ADDRESS/search/label/LABELNAME1/label/LABELNAME2

BLOG-ADDRESS is your full address such as http://blogname.blogspot.com or if you have your own domain then http://yourdomain.com
