 First you register each mapping name with its trigger(s). Remember the following:

-*  The mapping name is a string that you can choose. +The name should describe the action (e.g. “Rotate), and not the trigger. Because the trigger can change.
-*  One named mapping can have several triggers. +For example, the “Rotate action can be triggered by a click and by pressing the spacebar.

 Have a look at the code:
 
-.  You register the mapping named “Rotate to the Spacebar key trigger. +`new KeyTrigger(KeyInput.KEY_SPACE)`). 
-.  In the same line, you also register “Rotate to an alternative mouse click trigger. +`new MouseButtonTrigger(MouseInput.BUTTON_LEFT)`
+.  You register the mapping named “Rotate to the Spacebar key trigger. +
+`new KeyTrigger(KeyInput.KEY_SPACE)`). 
+.  In the same line, you also register “Rotate to an alternative mouse click trigger. +
+`new MouseButtonTrigger(MouseInput.BUTTON_LEFT)`
 .  You map the `Pause`, `Left`, `Right` mappings to the P, J, K keys, respectively.
