Boxsim's schematics - creating wires that miss connection points

Boxsim uses a grid of dots to create wires. Easy to use but only connects adjacent dots.
A number of the sample designs show wires that miss adjacent ones, curved or zigzags that pass over other wires.

Tried all sorts of key presses but no luck. Anyone know how to create these? Tried V1.2 and V2. No joy
