Mac 101: iTunes volume and a two-finger scroll
Here's a handy tip for MacBook Pro users* who listen to music with iTunes. While it's fun to listen to music while you work, the iTunes window takes up a lot of screen real estate. The quick answer is to minimize the window.
Here's the tip. With the cursor over the window, you can perform a two-finger scroll to adjust iTunes' volume. Scrolling to the right increases the volume; scrolling left turns it down.
Thanks, Anthony!
