I’ve blogged before (here and there) about keyword searches in Firefox. Keyword searches are great because they allow you to perform searches right from your address bar. Simply type your keyword (e.g. I use g for Google, a for Answers.com, wp for Wikipedia, &c.) followed by search terms and you’ll be magically whisked off to your search results. You can set up your own keyword for any site by right-clicking in any search bar and choosing “Add a keyword for this search” from the context menu. By setting up my own keyword searches, I’ve completely eliminated the need for the little search box to the right of my address bar, and, in fact, have removed it from my browser altogether.
Recently I discovered a service that takes this feature to the next level. YubNub, as the service is called, bills itself as a “(social) command line for the web,” and boy does it deliver. You can try the service out right away by going to the YubNub website, but it really becomes useful if you set it up directly in your address bar. I’ve got my Firefox address bar functioning as a YubNub command line, and I’ll mention later a few ways (and what I think is the best way) to do that. But first let me tell you more about the service.
