Many times my colleagues asked me how do I quickly open up a bug details in the browser  just by typing  a letter and the number and hit enter.It saves a lot of time as we skip one step always.The step might be either opening up the home page containing the form field or changing the search engine add on (accessible via Ctrl  +K ) .I added a Firefox bookmark keyword  today to open up WolframAlpha and give typed string as input automatically and compute on it. Here is the screenshot of the Bookmark from the Bookmark Library of the Mozilla Firefox.

Now after saving this bookmark when I type  (in the blank address bar ) “w <space> (23-5)/6” or any other expression computable in Wolfram|Alpha and Hit Enter, it opens up the results page having the input as (23-5)/6 automatically.

Alternatively following tools can be used for quick search and computation.
