The mode control buttons are arranged on the left-hand side of the Trainer bar. They offer you the following functionality:

• Previous / Next
  The buttons allow you to jump to a previous or following step.
  Alternatively, you have the option of selecting a step via the progress display.

• Pause / Continue
  The Pause button pauses the simulation. If the function is activated, the button switches to Continue.
  The function of the Continue button, if pause has been activated, is to resume the Playback of the simulation.

The associated status text is displayed along with the buttons. The status text indicates whether the simulation is running, whether Pause is activated at that precise moment or whether a step is being loaded.
