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

Given how you set this up, the way to do this is with /branch.

<trial instruct1>
/stimulusframes = [1=instruct1,arrow_key_continue]
/validresponse = (205)
/recorddata = false
/ branch = [trial.instruct2]
</trial>

<trial instruct2>
/stimulusframes = [1=instruct2,arrow_key_bidirectional]
/validresponse = (203, 205)
/recorddata = false
/ branch = [if (trial.instruct2.response==203) trial.instruct1 else trial.instruct3]
</trial>

<trial instruct3>
/stimulusframes = [1=instruct3,shape_grid, arrow_key_bidirectional]
/validresponse = (203, 205)
/recorddata = false
/ branch = [if (trial.instruct3.response==203) trial.instruct2 else trial.instruct4]
</trial>

(and so forth)

with

<block instructions>
/ trials = [1=instruct1]
</block>
