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).
On most HP and Compaq notebook computers, it is necessary to press and hold the function key (fn) while pressing one of the f1 through f12 keys to activate the default functions; such as, increasing or decreasing the brightness of the display, the sound volume, sleep, keyboard lock, etc. want the Fn key to be inverted... so that it is ON all the time, and pressing and holding it turns off temporarily. The reason is that the stupid multimedia controls now have priority on the F1 - F12 keys.
