Hot Keys

At the bottom of the screen you will find a list of the hot keys and their functions. Note: The functions of the hot keys change when the simulation is running.

The following hot keys are available when the simulation is not running:

• [F1 Help]

• [F2 Continue] simulation
• [F3 Offset | No Offset] --- toggle between showing the wave components on separate/same axes, for the Schrödinger and classical wave equations.

  [F3 Function | D/Dt] --- toggle between showing the function or its derivative, for the diffusion, Klein-Gordon, sine-Gordon, double sine-Gordon and phi-four wave equations.

• [F4 Step] --- proceed one time step, , forward in the simulation.

• [F7 Reset] restore the initial configuration of t=0.
• [F10 Menu] --- escape to the menu at the top of the screen.

The following hot keys are available when the simulation is running:

• [F1 Help]

• [F2 Pause]

• [F3] --- same as when the program is not running.
• [F4 Pos dT | Neg dT] --- this key acts as a toggle between positive and negative time steps, causing the simulation to run forward or backward in time.

• [F5 Faster] --- increases the speed of the simulation without affecting numerical accuracy by increasing the number of time steps between each redrawing of the screen.

• [F6 Slower] --- decreases the speed of the simulation without affecting numerical accuracy by adding (or lengthening) a Pascal PAUSE[t] command between time steps.
