How to use the bench (mouse, touch, or keyboard)
- Space pause / resume · R Record Data Point · 1 2 3 speed 1× / 5× / 20× · H help · L feedback-loop explainer · M microscope (radish).
- ← → move along any row of buttons (speed, dose, presets) and nudge any slider. Keys are ignored while you type in a box or a window is open.
- Microscope: Tab to the round view, then ← → to move between stomata, O = open, C = closed. With the mouse or a finger: choose Mark open ✓ or Mark closed ✕, then tap a stoma. Drag (or use the arrows) to pan when zoomed in.
- Record Data Point pauses the simulation and asks you to type what the sensors read. Your typed numbers go in your table; the sim keeps its own reading beside them.
