Hello everyone,

I would like to use an openended trial to let my participants write a short essay. However, I would like to disable the possibility for the participants to continue to the next page before they have spent a certain amount of time on the essay and I want to make sure they don't accidentaly go to the next page because they hit ENTER to create a line break. Is there a way to disable ENTER as a response that will terminate the openended trial (and use a timeout only)? It seems like this should be fairly simple, but I couldn't find anything in the help files....

Here's my code so far: 

<openended selfdescription>
/ frames = [1=selfdescription]
/ mouse=false
/ numframes=1
/ position= (50, 90)
/ numlines = 30
/ linelength = 100
/ charlimit = 1000
/ timeout = 180000

</openended>

Thanks!
