Have MediaLab create event markers?

I have read the section in the manual and know the TTL signal format, but where do you put the <.......> in the preference section?

If you want an event marker (or MediaLab to send a TTL signal) before and after the simulus is presented how would you write this?

Thanks!

It goes in the [I]parameters[/I] field in the [I]Details[/I] window of the given item, e.g., [I](<....>)[/I]. To send a signal before and after an item, include a signal for that item and for the subsequent one.
