I noticed that when I am using my chrome browser if I want to search the brwiki for something I can just click in the address bar and type "b" press tab and then type the term I want to search for and hit enter. It even auto-completes the terms for me with page titles from the brwiki. I thought it was nifty enough to share.
Note 1: If you type "b" and it's not enough, try typing "br" - it just needs enough to uniquely identify the wiki from other wikis you may frequent.
Note 2: My default search engine is google. I have not changed it to the brwiki.
Does this work for you too?
