Sure
test your keyboard.
Go to System Prefs, then Language & Text.
Go to the Input Sources tab, and check the box next to "Keyboard and Character Viewer"
You'll get a new icon in your menubar.Click on that icon, and click Show Keyboard Viewer.
You will then see an on-screen keyboard.
Press and release each key on your real keyboard, and each key will respond by highlighting then returning to off when you release. Try all the keys.
Hold the Shift key, or the Command or Option or Control, to see what each does to modify the rest of the keyboard. Press and release each number key, and you will quickly see if the keyboard is OK (or not)
The row of f-keys won't necessarily respond (because those keys have different purposes), but those are probably not related to what else you have.
