Keyboard shortcuts

Lab mode is keyboard-first for the actions you repeat while wiring. These are the shortcuts the app binds today.

Key	Action
R	Rotate the selection a quarter-turn clockwise (each part turns in place).
W	Switch between the Wire tool and the Select tool.
V	Switch to the Select tool.
Delete / Backspace	Delete the selected part, wire or parts.
Escape	Abandon a half-drawn wire, return to Select, and clear the selection.
Space	Run when stopped; otherwise pause or resume the run.
Ctrl/⌘ Z	Undo the last board edit (up to 200 steps).
Ctrl/⌘ Shift Z	Redo.
Ctrl/⌘ Y	Redo (the Windows-style alternative).
Ctrl/⌘ G	Group the selected parts.
Ctrl/⌘ Shift G	Ungroup the selected parts.
` ``	Toggle the developer overlay (frame rate, draw calls, component and net counts).

A shortcut is ignored while the text cursor is in a form field, the code editor, or the console: there, the keys belong to what you are typing. Letter shortcuts such as R and W also do nothing while a modifier is held, so Ctrl/⌘ R stays the browser's reload.

Canvas gestures

Gesture	What it does
Click a part	Select it; if it belongs to a group, select the whole group.
Alt-click a part	Select just that part, ignoring its group.
Shift-click a part	Add it to, or remove it from, the selection.
Drag a selected part	Move everything selected, in whole grid cells.
Shift-drag on empty board	Draw a selection box; enclosed parts are selected.
Click a wire	Select the wire for recolouring or deletion.
Scroll	Zoom in and out (0.25× to 8×).
Drag empty board	Pan the view.

The logic analyzer adds two more: click to place cursor A, Shift-click for cursor B, and the footer reads the time between them.

The inspector's empty state repeats the essentials — W wire, R rotate, Del delete, Ctrl/⌘ Z undo, scroll to zoom, drag empty space to pan — so you can recover them without leaving the app.
