What are Safety Precautions for Using Keyboard Properly

       Using your keyboard properly can help avoid distress or injury to your wrists, hands, and arms, particularly if you use your computer for long periods of time. 
Here are some tips to help you avoid problems:

 Place your keyboard at elbow level. Your upper arms should be relaxed at your sides. 

          Center your keyboard in front of you. If your keyboard has a numeric keypad, you can use the spacebar as the centering point.
            
              Type with your hands and wrists floating above the keyboard, so that you can use your whole arm to reach for distant keys instead of stretching your fingers.
 Avoid resting your palms or wrists on any type of surface while typing. If your keyboard has a palm rest, use it only during breaks from typing.

          While typing, use a light touch and keep your wrists straight. When you're not typing, relax your arms and hands.
 Take short breaks from computer use every 15 to 20 minutes.



 Make the keyboard easier to use

 
            You can use your keyboard to control the mouse and make it easier to type certain key combinations. Windows 7 make it much easier to control every bit of your computer, you can also adjust these settings to make the keyboard easier to use, follow the steps to do so:

1. Go to Control Panel and open Ease of Access Center.
2. Select the options that you want to use:

 Turn on Mouse Keys: This option sets Mouse Keys to run when you log on to Windows. Instead of using the mouse, you can use the arrow keys on your keyboard or the numeric keypad to move the pointer.

Turn on Sticky Keys: This option sets Sticky Keys to run when you log on to Windows. Instead of having to press three keys at once (such as when you must press the Ctrl, Alt, and Delete keys together to log on to Windows), you can use one key by turning on Sticky Keys and adjusting the settings. This way, you can press a modifier key and have it remain active until another key is pressed.

 Turn on Toggle Keys: This option sets Toggle Keys to run when you log on to Windows. Toggle Keys can play an alert each time you press the

Caps Lock, Num Lock, or Scroll Lock keys. These alerts can help prevent the frustration of inadvertently pressing a key and not realizing it.

 Turn on Filter Keys: This option sets Filter Keys to run when you log on to Windows. You can set Windows to ignore keystrokes that occur in rapid succession, or keystrokes that are held down for several seconds unintentionally.

 Underline keyboard shortcuts and access keys: This option makes keyboard access in dialog boxes easier by highlighting access keys for the controls in them.

 Prevent windows from being automatically arranged when moved to the edge of the screen: This option prevents windows from automatically resizing and docking along the sides of your screen when
you move them there.



 How to use On-Screen Keyboard

            Instead of relying on the physical keyboard to type and enter data, you can use On-Screen Keyboard. On-Screen Keyboard displays a visual keyboard with all the standard keys. You can select keys using the mouse or another pointing device, or you can use a single key or group of keys to cycle through the keys on the screen.

              Go to Control Panel, open Ease of Access center and select On-Screen Keyboard.
 To use the On-Screen Keyboard, select the mode you want, following modes are available:

Important things to Remember

              If you're using either hovering mode or scanning mode and accidently minimize On-Screen Keyboard, you can restore it by pointing to it in the taskbar (for hovering mode) or by pressing the scan key .
 If you're using a mouse click to select a key in the Scan through keys mode, the mouse pointer must be located over On-Screen Keyboard.
 The keyboard layout changes in On-Screen Keyboard depending on the language displayed in the active program.
