Ending a Slide when condition is met

Actually, I do have the code for the calculation of the 1500ms but I
do not know how to simulate a key press to terminate.
Thank you

Basically, the slide should be 0 ms (so that it refreshes continuously) with a TETWaitForFixation (or something of the sort) after this. In the properties of this package-call, you set 1500 ms, which means E-Prime will only continue if the person is fixating (without interruption!) for 1500 ms. This, in turn, I believe is internally done with simulating key-presses. The tutorial on Tobii Extensions for E-Prime is something you should definitely not skip (I did, so do like i say, not like i do - i regretted it anyway!)
