The following set of instructions for using a PC includes a basic introduction to the keyboard, mouse, desktop, and Windows. The keyboard is where you do your main typing of letters, numbers, and other special keys. The mouse is the device that you use for most interactions with your PC and works in synergy with the keyboard. You can move the mouse around the screen, which appears as a pointer arrow, to select and activate options. Windows is the main operating system that runs all of your programs on your PC. The Desktop is the main background on your screen and is where you will start your navigation to other programs.
Press Windows Key on your keyboard to open Start Menu and Press Windows Key again to close the Start Menu.
On the keyboard, for windows systems, you press the indows key (has the windows symbol on it) and the letter 'D'. This should minimize all windows and show the desktop. Alternatively, you could press the windows key and then select all the programs/windows from the taskbar itself.
Is the keys on a laptop or desktop? Is on a desktop they just pop off real easy and you can replace them with new keys. If it is on a laptop they are a little harder and require some work.
[windows key] + [D] - will minimize all the windows and show your desktop. Pressing it again will bring the windows back up. Note: You have to press the keys at the same time. If you're having trouble, hold down the windows key, and keep it depressed, and tap the [D] key.
Hold CTRL and ALT keys down simultaneously, then tap each arrow key till you find the one that starts rotating the screen. Rotate the screen till you are satisfied.
Hold Alt then either the arrow keys or the arrow keys on your num pad will flip your desktop.
In Windows, double-click on the Excel icon or right-click on the icon and select OPEN. On the MAC, single-click (MAC) on the Excel program icon (the same way you would open most other programs).
You probably mean the Print Screen button, sometime abbreviated Prt Scr. It varies by keyboard, but a typical desktop 103-key keyboard has it in the cluster at the end to the right of the function keys above the dedicated cluster of "arrow" keys.
With the three Microsoft Windows keys, function keys, and the keys found on the number pad the standard Windows US keyboard has 104 keys. The standard Mac wireless keyboard with no number pad has 78 keys.
