The Workspace has a central role inside the program.
Graphical elements (modelements) of the chains, steps and transitions are displayed and can be edited.
The case and each chain has its own drawing. So there can be for the case and for each chain a different tab in the Workspace.
The interaction with the drawing happens with the mouse.
New chains, steps and transitions can be added with the Toolbar
and the OperatorTools.
Existing modelelements can be selected with the mouse in the drawing of the case or of the chain
and in the Navigator.
To delete selected elements you can press "DEL" or by selecting the element with the mouse and pressing the right button.
Then a popup-menu opens where you press "Delete".
Take care, if you delete a chains all steps and chains in the chain are also deleted.
