Rated 3 out of 5 stars
What I wanted: the addition of my search engines to the right-click context pop-up, so I wouldn't have to mouse up to the search box and change the search engine for a one-off switch between engines.
My search engine is usually on Google, but sometimes I want to search with, say, Wikipedia or Worldcat.
With SearchWith I can do this, but there's a lot of other stuff I don't want, which makes the user interface more oblique than it would be with the simpler concept. And then there is this strange indirection, with "services" instead of just search engines. I'm sure there's a good reason for that, and it is quite likely that many other users really love all that other stuff, which is fine: I just wish there was a smaller, cleaner option.
I poked around and discovered that "Auto Context" does what I want with a little less fiddling, so I'm using that instead. HyperWords look fascinating, but currently is way more than I want.
But the tool seemed to work fine -- just too fancy.
