DirectedEdge[u,v] or uv

represents a directed edge from u to v.

DirectedEdge[u,v,t] or uv

represents a directed edge from u to v with tag t.

Details

DirectedEdge is also known as arc or directed link.
DirectedEdge[u,v] can be input as uv. The character  is entered as de or \[DirectedEdge].
DirectedEdge[u,v,t] can be input as uv. An empty template can entered as tde, and moves the cursor to the overscript position.
