Mac OS X Help: Specifying criteria in Spotlight

I just updated this post with a Mavericks screenshot, but the basic point holds true for the past few versions of OS X: the Spotlight search tool on Macs can be very powerful, but a surprising number of people don't seem to know how to tap that power (and for a long time that included me).

Apple has a good basic article on Spotlight. Remember that you can always press Command+Spacebar to pop up Spotlight. And you can use the Spotlight pane in System Preferences to change these categories around, their order, and even which categories appear.

You can type calculations into Spotlight and find that 256*2-680 is 168.

You can get the definition of a word by typing it into Spotlight and then checking the Look Up section of the results.

Enjoy!
