Firefox Dynamic Bookmarking

If you're like me who uses the Firefox history to quickly access pages, you're more than likely to search for a link in the dropdown, modify it a little and then view it.

An example is viewing bug tasks in Trac.
At work, ticket numbers get passed around rather than the whole link.
I tend to type in "trac" so the Firefox Awesome Bar returns a few results.
I select the result that closely resembles the ticket url, and then modify the ticket ID so it takes me to the ticket I want to view.

Now imagine that could be quicker.
Luckily, Firefox supports bookmark keywords which DOES make it quicker!
I can just type "trac 1234" and it'd take me to that very link.

For example, the link http://www.youtube.com/watch?v=HXi-8nLK_dc

1. Bookmark the page and edit it.
2. Edit the link so you keep the "http://www.youtube.com/watch?v=" chunk, but replace the video ID with "%s" so it becomes "http://www.youtube.com/watch?v=%s"
3. Give the bookmark a keyword such as "yt"
4. Test by typing "yt HXi-8nE65JshkU" into the Firefox address bar.
