How can I move the Windows 8 on-screen keyboard?

The keyboard you are using has two modes - docked and undocked:

• In docked mode, the keyboard locks to the bottom of the screen, as per your screenshot.
• In undocked mode, you can drag it around the screen as necessary.

To switch between the two modes, click this button:

Alternatively, you can use the on-screen keyboard that used to be an accessibility feature in previous versions of Windows. To launch this, open the Start screen and type keyboard, then select this application:

This will appear as a desktop window instead, and has a larger choice of buttons:

1. Press the "Options" key.
   

2. Check the "Show keys to make it easier to move around the screen" option.
   

3. Use the navigation keys to move the keyboard.
   

Note that if I search for "keyboard" from the Start Screen, then select the "On-screen keyobard" app, it appears in a window that I can move around. I am using full Windows 8, not Windows 8 RT, so this may have something to do with it.
