Be sure to visit the Trace Modeler website for updates and UML sequence diagram resources!
To change the target order simply reposition individual targets, either with the keyboard or the mouse.
You can only change the message order in diagram edit mode.
With the mouse
- LEFT-DRAG the target to where you want it to be placed and then release the left mouse button to drop it there. You needn't worry about the exact drop location, only its relative position to other targets is important.
With the keyboard
- Select the target
- Use the LEFT ARROW and RIGHT ARROW keys to swap positions with one of the targets next to it.
You can also let Trace Modeler optimize the target order based on some heuristics.
