The first click starts a wire, which already has two segments, one
horizontal, one vertical, with the first segment being the longer one
initially.

Moving the mouse then adjusts the length of both at once. If the first
segment disappears, they switch places (so if you start horizontal and
pass through the point over the beginning, the vertical segment becomes
first).

Clicking fixes the point between the two segments currently being
edited, and adds another segment at the end, which then has to be at a
90 degree angle.

Clicking on a connection point (end of another wire or end of a
component pin) ends the wire. If you want to end the current wire
without connecting anywhere, double-click.

When you move a component ('m' key), nothing else moves. When you grab a
component ('g' key), all wires that are already connected remain
connected, and the last segment that connects to the component is adjusted.
