Getting started

• Place: choose a component on the left, then click the canvas.
• Wire: drag from an output pin (right) to an input pin (left).
• Move: drag any component body to reposition it.
• Flip a switch: click an Input Switch to toggle it on/off.
• Select: click a gate or wire; drag an empty area to box-select. Shift+click adds.
• Delete: select, then press Delete.
• Undo / redo: Ctrl+Z / Ctrl+Y. Duplicate: Ctrl+D.
• Rename: right-click a gate (or double-click it) to add a label.
• Pan: drag with the middle mouse, hold Space, or two-finger scroll.
• Zoom: pinch, or hold Ctrl and scroll.
• Amber pin: an unconnected input — it reads as logic-low.
