Links are used to join nodes in a Workflow Process. You can select either a direct 
or an angular 
link. Once selected, hover over a node, select one of the four connection points then drag the link to one of the connection points of the next node.
If a link becomes detached from a node, the detached end will turn red and need to be reattached.
A link can be renamed by double clicking on the link.
Links can be changed from direct to angular using the right-click menu option (Link > Set link angular) or (Link > Set link direct).
