click the smarT.NC soft keys with the mouse
If multiple soft-key rows are present (represented by lines directly
above the soft keys), you can activate a row by pressing the
corresponding line
In the tree view, click the arrows pointing to the right to show detail
forms, and click the arrows pointing down to hide them again
In order to change values in a form, click any input field or option box,
and smarT.NC automatically switches to editing mode
To exit the formula again (to end the editing mode): Click anywhere in
the tree view. Then smarT.NC asks whether to save changes in the

If you move the mouse over any window element, smarT.NC displays
a tooltip. The tooltip contains brief information on the respective
