Taking right clicking for granted

[Zack777]

My wireless mini mouse ran out of batteries, and I don't have any more batteries. Do I have to use my old black apple mouse back from the PowerMac G4 days, no scroll, one button  I'v been using my trackpad over the school year when I had to carry around my Macbook, but since its the summer, and I'v been sitting in front of my Macbook, I started using  a wireless mini mouse with right click.
