I’m all for efficiency. And as someone who works primarily on a laptop (and sometimes in various locations without all my ideal equipment), it truly makes my day when I come across some computer hack that cuts my time in half.

Want to know my secret? I’ll give you nine—that is, nine super-simple PC shortcuts that will make using a mouse look like child’s play (even if you’re used to using a Mac at home).
