This is essentially a {{w|Jog dial|jog dial}}, or similar {{w|Rotary encoder|rotary encoder}}. These are sometimes used with keyboards: as controls for volume, video editing, or drawing. | This is essentially a {{w|Jog dial|jog dial}}, or similar {{w|Rotary encoder|rotary encoder}}.

โ | Many computer keyboards have four {{w|arrow keys}}: up, left, right, and down. However, the XKeyboarCD just has one that can be rotated. This has the added bonus of allowing the arrow keys to point more than four different directions. In a keyboard, it would be awkward to operate as going from horizontally left to horizontally right, for example, would require the user to rotate the key first and then press it, which wastes precious time when playing a video game like [http://explainxkcd.com/1608 the hoverboard comic], where you have to rapidly press arrow keys to move around. It would not let one press multiple arrow keys at once. | + | Many computer keyboards have four {{w|arrow keys}}: up, left, right, and down. However, the XKeyboarCD just has one that can be rotated.
