Fellow speaker,
If someone heckles you, pay attention to what the person says. If their idea is on target with your speech, repeat what they said, thank them for the idea, and then physically turn your back to them or turn away from them to indicate that they have had their "stage time" and now it is time to return to your presentation. If their comments are NOT on target with your speech, thank them for the idea, mention it is not what you are focusing on now, and say you can discuss this with them AFTER the presentation.
Deheckelfying,
Tim
