Sending triggers: how to best invoke them?

[J. Scott Saults]

Sorry, but I hadn't read the message by Paul Groot before posting my 
code, so I hadn't thoroughly considered that option.  I want to 
continue, not terminate, the display,  but that can be accomplished 
anyway, as his code shows). Would that method (sending at termination 
rather than looping to poll the keyboard) be more accurate?

Does anyone have information to help evaluate methods for sending 
realtime response triggers that include accuracy &/or response data?

Thanks.
