--vcommand allows the correct positioning of labels along the shaft of arrows.
+-command allows the correct positioning of labels along the shaft of arrows.
This feature is sometimes necessary, when the default position of a label
would otherwise clutter the picture, or would even coincide with other
items, such as the intersection of the arrows in the figure below.
In order to shift a label position alongside the shaft of an arrow,

A more general trick uses invisible arrows to place any object almost anywhere
inside a diagram.
Produce an invisible arrow, shorten (or prolong) it past its goal by adding
