I have been using Google Chrome more and more lately.  Today I came across "Paste and go."  I had a URL on my clipboard and right-clicking in the universal bar presented both the option to Paste and Paste and go.  Sure enough, Paste and go pasted the URL into the bar and went. 

I <3 Google, the only thing missing is a hotkey combonation for it.  I guess Ctrl-V + Enter works, but where is the fun in that.
