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).
For the Fn key and the function key to work it must be supported by the computer and device. For example, if you are pressing the Fn key and the brightness key to increase the brightness it only works on the laptop screen and not an external monitor connected to a laptop.
