Hello, is there a way for me to add a prevkey and nextkey in a trial?
I created instructions using text and trials because for some of the instructions I want it to timeout (without giving a response), others I want to be able to do only the next key (like a welcome page), and others I need both a previous key and next key. These instructions also include pictures, and the order of the instruction screens isn't in a way where I could bunch them together based on whether they use a prev. or next key, because it goes back in forth in some cases. Therefore, I don't think using pages and the instruct element is appropriate in this case.
I have included code for the instructions. The code below isn't usable because it recognizes left and right arrow key to move, but only to move forward. So the distinctions that I have made for bidirectional (prev. and next) vs. continue (next key) aren't possible. Do you have any solutions? I would greatly appreciate your help!
Thank you
