+There may also be **several transitions the same way round** between two states, `alarm` and
+`seen` from *Patrol* to *Chase*, say. They are told apart only by their name, so a further one is
+given a name of its own the moment it is made (`Transition 2`, `Transition 3`, skipping any name
+already leaving that state), and the inspector refuses a rename that would make two of them alike,
+the empty name included. They are drawn side by side like a there-and-back pair. In a behavior
+graph a second edge between the same two ports is still refused (`Already connected`).
 
 A transition may also lead from a state **back into itself**: after *Make transition*, click the
 same state again. It is drawn as a **loop over the top edge** of the node, and the inspector lists
 it once, under *out*. Taking it **re-enters** the state: `On state exited` and then

 A transition can be **named**. Select a state and the inspector lists its transitions in two
 groups, *out* and *in*, each row with the state at the far end, a name field and a button to
