HELP: feedback set up for mobile usage ANT

I am hoping someone could help with some advice for my problem

I need arrow buttons in an Attention Network task, so it’s device agnostic and mobile compatible and the arrows should be linked to the feedback on reaction time, that reacts to either the arrow buttons of mobile usage or keyboard if done on a computer.

Your help on any of these topics would be massively appreciated :slight_smile:
