In this example, along with the built-in commands, few custom commands are added. Few built-in commands(nudge) are overridden. That is, when the arrow keys are pressed, selection will be navigated instead of moving the selected objects. The different kind of interactions and the corresponding key gestures are listed in the property panel.
