1 A wild turkey has excellent vision and hearing. There field of view is about 270 degrees.Thisis the main reason they continue to elude some hunters.  A spooked turkey can run at speeds up to 20 miles per hour. They can also burst into flight approaching speeds between 50-55 mph in a matter of seconds.
When you often use a function from the menu bar often, the shortcut is usually next to it. Ok, then: fn (function) is meant for the function keys f1-f12 (or more on larger keyboards). It's pure meaning is to switch between the usual f-behaviour and OS X functions (media control, brightness, etc.). It's also used for controls that are potential standard-keys but don't fit on the smaller keyboards (a larger [USB] keyboard from apple for example has a delete key, to save space the smaller keyboard put's it on a fn-function).
Keys with symbols of the same color indicate that their secondary function will be activated by pressing them while holding the Fn key down. In this example, you can see that pressing and holding down the Fn key, along with the up or down arrows, would adjust the brightness. Tip: The Fn key is almost always located in the bottom left-hand side of the keyboard, next to the Ctrl key. However, it may also be located to the right of the spacebar on some keyboards. Tip: The Fn key should not be confused with the Function keys F1 - F12 found on all computer keyboards.
