| Simulator Background Properties: To open the simulator background Properties Box, depress Select. Then double-click or control-click in a clear area of the simulation window. In the Substance Region, you can determine if substance piles, lumps and scoops show the substance name only, show both the name and symbol, or hide the substance label. You have the same three choices in the Small Particle Region for particles. In the Chemistry Analyzer Simulator, you can also choose to not show the Substance Decomposer (Substance Analyzer) or the Particle Decomposer (Particle Analyzer) by unchecking the appropriate boxes. In the Chemistry Reactor Simulator, you can also choose to not show the Substance Synthesizer (Substance Reactor) or the Particle Synthesizer (Particle Reactor) by unchecking the appropriate boxes.
