Selection

A node is selected when it is clicked on. This will deselect anything currently selected. The Information Sidebar will update to show the node’s properties and help text for its type.

If the Ctrl or Command key is held when clicking on the node, the node will be added to the current selection (or removed if it was already selected).

If the Shift key is held when clicking on the middle of the node, it will select that node and all other nodes it is connected to. Clicking on the left-hand side of the node, it will select that node and all nodes that come before it in the flow - “upstream” nodes. Clicking on the right-hand side of the node, it will select that node and all nodes that come after it in the flow - “downstream” nodes.

A wire is selected when it is clicked on. Unlike nodes, it is only possible to select one wire at a time.
