Select the appropriate message in a Sequence diagram.


Use the mouse to drag the message up or down as required.

As you drag a message up or down a lifeline, any messages or fragments below that message are shifted up or down the same amount.

If you press and hold Alt as you drag a message up or down past the next or previous message, the messages swap positions, rather than simply move position.

As you move one Message past another, a tooltip displays to remind you to press and hold Alt, regardless of whether you are actually pressing the key. You can hide this tooltip by deselecting the 'Enable tooltips when reordering messages' checkbox on the 'Diagram | Sequence' page of the 'Options' dialog.
