browse select text, text at point

[smclean0640]

Hello,

I am wondering whether anyone in the group knows a package that will
accomplish the following: 
- I am on a word, say "limousine", by pressing a keystroke I can browse
  this word in google (or a chosen search engine) with my default browser,
- I have selected a region of text and I want to search that text in my
  default browser.

Any ideas as to how to most effectively accomplish this? Downloading a
packaged would be ideal, but I am willing to try my hand at elisp.
