I spend a lot of time typing in that little box in the upper right corner of my browser - the Google search box that suggests keywords as you type. It's simple to use and helps me frame my searches even before I press Enter.

I use the search box for much more than traditional searches. I use it as a calculator and to convert hectares to square miles. I also use the search box to help with spelling, by beginning to type a tough word and seeing what spellings Google suggests.

So I was watching this fascinating yet maddeningly quirky video of Verbatim author Erin McKean, and she said her favorite word was "erinaceous." Naturally, I guessed (wrongly) at the spelling in the search box [define erinacious].

It's a little thing, but it's new -- now Google gives you "did you mean" spelling corrections as you type in the search box, without ever opening a browser window. So cool!
