It will bring back a page and the Free Virtual Keyboard is listed first. Look to the right of it and click the Download Now button. Download and install it.

It's a neat keyboard to have just in case your real keyboard goes bonkers. You simply click on the letter with your mouse pointer that you want. It has all the functionality of a physical keyboard. You can open a web page, place your mouse in the address line then bring up the virtual keyboard by clicking on it from your desktop or start menu and it will sit on top of whatever you were trying to do. You can move it to see the typing area as you click on a letter. It works the same way if you opened a word document. In your case anytime you need the space bar, just click on it.
