When you are constructing your HUGIN network, you are running in
edit mode. In figure 1 you can see a network window of a HUGIN network running
in edit mode. In edit mode, the network
window is split up in a node edit
pane containing the table of the currently active node. Below the
node edit pane is the network pane where the graph describing the
network is found.

HUGIN network running in edit mode.
You go from run mode to edit mode by pressing
the edit mode tool button (see figure 2).
