Drag the empty canvas to pan, scroll to zoom (or use the toolbar / Ctrl/Cmd + scroll). Drag elements to move them — drop a function inside a component or node to allocate it. Hover an element to resize it (corner handle), create an exchange (blue handle) or delete it (red handle). Click an element to see its traceability links. Double-click to rename; double-click an exchange to name it. Ctrl/Cmd+D duplicates, Suppr deletes, Ctrl/Cmd+S saves.
