Hi Blair

Thanks for creating that feature! I downloaded and installed the new version and it works great. In the interim I had figured out another way of doing it, using jumping to different trials depending on which response was made, and sending codes (followed by presenting a "space" character for 0 msec) from the jump trials. But, the TTLecho method is far more flexible and saves one from coding a lot of jump trials if there are many response options.

It would be great if this could be integrated into the Styles file in a future release, rather than being dependent on an extra file.

thanks again, DirectRT rocks!
