UndirectedEdge
UndirectedEdge[u,v] or uv
represents an undirected edge between u and v.
UndirectedEdge[u,v,t] or u
v
represents an undirected edge between u and v with tag t.
Details
- UndirectedEdge is also known as link or connection.
- UndirectedEdge[u,v] can be input as uv. The character is entered as
ue
or \[UndirectedEdge]. - UndirectedEdge[u,v,t] can be input as u
v. An empty template 
can entered as 
tue
, and 
moves the cursor to the overscript position.
