How do I Change Function Key Behavior on My MacBook Air?
How can I set up my Mac so I don't have to press the FN key in conjuction with the Function Keys to get a normal press instead of using them to raise and lower volume?
You want to open System Preferences, open the Keyboard section, and choose the first tab. There's a checkbox that says, "Use all F1, F2, etc keys as standard function keys". Uncheck that, close System Prefs, and that should do it.
