GATE FORGE
Drag a gate body to move it.
Click an input switch to toggle it.
Drag from a pin to another pin to wire.
Shift+click a pin, move away (no need to hold the mouse down), then click a compatible pin to finish the wire — handy for long-distance connections. Escape or clicking the same/an incompatible pin cancels it.
Drag on empty canvas to box-select multiple gates; Shift-click or Ctrl-click to add/remove one.
Right-click any gate (or selection) to rename, duplicate or delete — right-click an Output LED to also pick its colour.
Select, then press Delete.
Pick Pencil or Auto Pencil in the top toolbar to draw notes on the canvas — these are never part of the circuit. Switch back to Select to keep editing gates.
Build a circuit, then Save Component to turn it into a new reusable gate under "Saved circuits". Export keeps it for later sessions — only the canvas (circuit + annotations) is exported/imported, your saved circuits stay untouched.
Use the zoom controls (bottom-left of the canvas) to zoom in or out; Reset returns to 100%.

Keyboard shortcuts
- Ctrl/Cmd + A — select all gates (Select tool) or all annotations (Pencil/Eraser/Text tool)
- Ctrl/Cmd + Shift + A — select everything at once: every gate/circuit and every annotation
- Ctrl/Cmd + click — add/remove one gate from the selection (same as Shift-click)
- Ctrl/Cmd + C / X / V — copy / cut / paste the current selection
- Delete / Backspace — delete the current selection
- Escape — clear the current selection
- R — rotate the selected gate(s)
- Ctrl/Cmd + Z / Ctrl/Cmd + Y (or Ctrl/Cmd + Shift + Z) — undo / redo
- Click empty canvas — deselect everything
Other options
- Zoom controls (bottom-left) — zoom in/out with a live percentage, or Reset to 100%; the whole canvas, including annotations, scales together
- LED colour — right-click a lit Output LED for a row of colour swatches; green is the default
- Wire colour — right-click any wire to pick a colour; it stays grey until chosen, shows a dim shade at 0-logic and a bright shade at 1-logic
- Table button in a text note's toolbar — inserts a bordered rows × columns table, handy for truth tables
- Gate symbols — each entry in the Gates palette now shows its standard logic-gate shape next to its name
- Push button (I/O section) — outputs 1 only while held down on the canvas, releasing snaps it back to 0
- Glow sliders — the LED colour menu and a wire's right-click menu both have a 0-100% Glow slider (0% is flat, 100% is a wide bright halo)

Truth table tester
Detects every input switch and output LED on the canvas, builds every combination, and checks it against a circuit you run.
Timing diagram
The same rows as a waveform — inputs, the reference values you typed above, the simulated outputs, and where they differ. Scroll sideways if it runs long.
