A very useful feature of the editor is the branch tool. By selecting
Tools/Insert branch or the button on the toolbar, you can
extend the graph-program by adding a branch. What is a branch? It is simply
an arrow that links the selected instruction to another. The inserting
of the arrow and the new instruction is made in just a step. Choose the
"destination" instruction and fly over the "source"
instruction. The shape of the cursor suggests the direction of the branch
- if any - like in the figure below. When you click, the branch appears.
