proceeding to next trial after some time or key press

Hi,
i have an experiment where I show a phrase of a few words, word by word, each word for 80ms. the participant needs to press a key when he/she have identified the word.

I built an input file that displays every word for 80 ms and then waits for some key press. however i would like to allow for the participant to press the key even BEFORE all the words appeared. i.e. i would like that from the moment the word was displayed (but not before!!!!) that pressing a key would advance you to the next trial, and the response time is recorded (from the beginning or from the moment the word was displayed i can compute it afterwards.

I tried to find some 'or' operator (e.g. "RT: any || 80") but it didn't work.

please help!!!
thanks
Jonathan

It sounds like what you want could be accomplished by using a min-max value in your style file of [I]0-80![/I] and then specifying [I]rt:any[/I]. See [I]min-max[/I] in the user's guide for details.
