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).
Press the Fn key, normally located in the lower left corner of the keyboard next to the CTRL key, and the F11 key at the same time. Depending on the particular Dell laptop model, the F11 key may say Num Lock or may have an icon of a keypad.
