In each timeline the events are displayed chronologically, The time has a quantization unit and then beats and bars and assigned as multiples of the quantization unit. These are marked on the display. Events can be displayed on their own line according to what OSC message/Expression they output.
The current selected event on the timeline is marked with a blue square. Clicking on an event selects it and the event can be dragged over the timeline to position it, and its data is shown above it. Once the event is selected it can also be moved with keys:-
| Key combination | Function |

| shift + arrows | moves 1 beat (drag snap the beat by default) |
| shift+ctrl+arrow | moves one bar (ctrl+ drag snaps to bar) |

Clicking on the timeline selects it as the current timeline which receives keyboard focus.
