Shifting diagram elements with the mouse

You can use the following mouse actions to shift all or some of the elements in a sequence diagram.

Shifting the entire diagram in vertical direction

Verify that an instance line is not currently selected.
Position the mouse in the area over the classifier role names.
Press Shift and drag the mouse up to shift the entire diagram upward, or drag down to shift the entire diagram downward.

Verify that an instance line is not currently selected.
Position the mouse over the highest element that you want to shift.
Press Shift and drag the mouse in the direction that you want to shift the specific element and all the elements following it.

Select any of the instance lines in the diagram.
Position the mouse to the left of the instance lines that you want to shift.
Press Shift and drag the mouse in the horizontal direction that you want to shift all the elements.

Note: If you place the mouse on an instance line and drag while the Shift key is held down, the product shifts the instance lines in a direction of that instance line but not that instance line itself. On an instance line includes the entire width beneath the box that contains the name of the classifier role.
