Search from IE address bar
Following registry entries (copy the registry stuff below to a .reg file and import it), will allow you to type something like "g Boston" in the address bar and have it search using google web. "gg Boston" will search Google groups.
You might have already done this stuff. But, if not, this can be pretty handy.
