I am getting really addicted to Open Shortcuts in conjunction with the search bar in Firefox. For example, just type
!wiki bangalore and it'll search wikipedia for you without having to do the 3-step process of opening wikipedia.org, then entering the search query and clicking on 'go'.
You can create your own shortcuts as well. Just login to yahoo search, and run
!set dict http://dictionary.reference.com/search?q=%s, next time just type
!dict anthropomorphize and it'll take you to the search results page directly. The best part is that this now works from any browser and computer that you use.
To get to know the list of shortcuts you can use, just type
"There are no shortcuts in life, unless you right click and find one."
