Specifying the Position of Agent and Speech Bubble 
Use
In the Editor, you can specify where the agent or speech bubble should be positioned for each step. You can also specify which gestures the agent should make.
Procedure

You can position the speech bubble independently of the agent.
You can change the position of the speech bubble’s pointer. Call the context menu of the speech bubble and select a pointer position.

The standard position of the agent is to the right of the interaction area. If you move an interaction area or change its size, the agent’s position is automatically adjusted accordingly.
Result
You have specified the agent and speech bubble settings for the step selected or multi-interaction step.
