One of the Shwa keypads offers cursor keys, and when so used, they have standard meanings, standard symbols and a standard layout. On the Cursor keypad, each key counts on its own, not as part of a keypair.
To show the Cursor keypad, press the √ key, then the Cursor key.
Here's the cursor keypad. Take a look at it, and then we'll explain the keys.
These 20 keys enable simple movement, full movement and rotation around all 3 axes: front-to-back (longitudinal), side-to-side (lateral) and top-to-bottom (vertical). They always take the point of view that you are moving, not the background. The icons ask you to imagine yourself as a cylinder: a round dot when viewed from above, a rectangle when viewed from the side or the back.
Let's start with the dot surrounded by a circle. This is the Stand key, used to stop motion or to mark the current position.
The four keys around it offer simple Movement in the four directions: Move Forward (on top), Move Back, Move Left and Move Right. In this notation, the dot represents the starting position, and the line moves away from it.
The four keys whose line ends in a T offer full movement, as far as you can go. For example, Full Left is the equivalent of the Home key and Full Right is the equivalent of the End key.
Meanwhile, the two keys with curved lines offer Turn Left and Turn Right, which don't move you - they just change the way you face. To move left, you could use the Move Left key, or you could Turn Left and then Move Forward.
The final dotted key is Center. It might bring you back to a starting position, or just line you up along the axes.
The four rectangular keys in the first column are Full Up, Move Up, Move Down and Full Down, as you could probably guess.
The two final keys in the top row show you from behind, Roll Left and Roll Right.
Finally, the two final keys in the bottom row show you from the side, Tilt Up and Tilt Down.
Here's a recap of the cursor keys :
