In this article I will show you how to open and select the new layout of On Screen Keyboard in Windows 8. On-Screen allows the users as an alternative virtual keyboard that can be used through the pointer device like the mouse. It is helpful when the actual physical keyboard doesn't work properly. The On-Screen Keyboard displays a virtual keyboard on the computer screen that allows people to type data using a pointing device or joystick.

We can also adjust or change the layout of the On-Screen Keyboard as suitable. You can adjust the layout, alignment, or number of keys that appear in the On-Screen Keyboard. There are many ways to open the On-Screen Keyboard. Step 1 Move the pointer on the right-bottom of the screen and select the Search option. Step 2 In the search box, you can type the name "On-Screen Keyboard" and search it. Note: A PC with a touchscreen also has a touch keyboard.

The touch keyboard will appear when you tap inside a text box when your PC is in tablet mode. A keyboard that can be used to move around the screen and enter text will appear on the screen.

The keyboard will remain on the screen until you close it. Note: To open the OSK from the sign-in screen, select the Accessibility button in the lower-right corner of the sign-in screen, and then select On-Screen Keyboard. With the OSK open, select the Options key, and choose the options you want:.

Use click sound : Use this option if you want to hear a sound when you press a key. Show keys to make it easier to move around the screen : Use this option if you want the keys to light up as you type. Turn on numeric keypad : Use this option to expand the OSK to show a numeric keypad. Click on keys : Use this mode if you prefer to click or tap the on-screen keys to enter text. Hover over keys : Use this mode if you use a mouse or joystick to point to a key.

The characters you point to are entered automatically when you point to them for a specified time. Scan through keys : Use this mode if you want the OSK to continually scan the keyboard. Scan mode highlights areas where you can type keyboard characters by pressing a keyboard shortcut, using a switch input device, or using a device that simulates a mouse click. Use Text Prediction : Use this option if you want the OSK to suggest words for you as you type so you don't need to type each complete word.

If you want to use one of these languages and it isn't installed, install the language files for that language. If you're using either hovering mode or scanning mode and accidently minimize the OSK, you can restore it by pointing to it in the taskbar for hovering mode or by pressing the scan key for scanning mode.
