With Windows 8.1, you can use different keyboards to fit your needs. The most common keyboard is a physical, external keyboard that you connect to your PC. Windows 8.1 also includes a touch keyboard for PCs with touch.
If you want to open the touch keyboard manually (without tapping in a text field or other area where you can type), here's how:
Swipe in from the right edge of the screen, then tap Settings.(If you're using a mouse, point to the bottom-right corner of the screen, move the mouse pointer up, then click Settings.)
Tap the Keyboard icon.
Tap Touch keyboard and handwriting panel.
As you use the touch keyboard, Windows might provide text suggestions to help you enter words more quickly or to correct misspellings. To insert a suggestion, tap it, or, if it's highlighted, just press Spacebar. To switch the highlighted word, swipe right or left on the Spacebar.
Here are a few tips and tricks to help you get the most out of your touch keyboard.
At the end of a sentence, double-tap the Spacebar to insert a period and a space.
Press and hold keys to see similar characters. For example, pressing and holding "e" reveals è, ē, é, ê, and ë.
Flick up on any of the keys in the first row (the row that starts with QWERTY) to insert the corresponding numbers (located in the top left of the keys).
Tap the "&123" key to switch to the numbers and symbols view. You can switch to and from the numbers and symbols view more quickly by pressing and holding the “&123” key, tapping the keys you want, and then releasing it.
Turn Caps Lock on by double-tapping the Shift key.
Use keyboard shortcuts by tapping the Ctrl key and then tapping another key.
If you're looking for some fun characters, tap the Emoticon key.
