For those of you who miss using quick command-line shortcuts to accomplish tasks, this post by Lifehacker might be for you. I have to admit that sometimes it is more trouble that it is worth, but I also like the ability to quickly add something to my google calendar without going through 5 clickes to even get to the page.
It works like this: when you enter text on a web application, the result is often the web page sending that text along to a server as part of a URL. A Google search for lifehacker android results in a URL of http://www.google.com/search?q=lifehacker+android. By finding the right URLs—for Google Calendar events, Google Maps directions, Twitter statuses, and more—we can use keywords in the address bar to submit text to any of those web sites.
