Marking Blocks in the SFC

A marked block is a bunch of SFC elements that are enclosed in a dotted rectangle.

You can select an element (a step, a transition, or a jump) by pointing the mouse on this element and pressing the left mouse button, or you can use the arrow keys. In order to mark a group of several elements, press <Shift> for a block already marked, and select the element in the lower left or right corner of the group. The resulting selection is the smallest cohesive group of elements that includes both of these elements.

Please regard, that a step can only be together with the preceding or the succeeding transition !
