Hello!
OS (e.g. Win10): W10
PsychoPy version (e.g. 1.84.x): 2023.2.3
Standard Standalone? (y/n) Yes
**What are you trying to achieve?: I would like to display different letter on screen and I would like to record a no key press as a correct answer for one particular letter (X letter), for the ohter letter, space bar is the correct answer.
**What did you try to make it work?: I created a xls file with all my letter in one column and the correct answer associated in an other column, i put space for all the letter but i don’t know what to write for the X letter.
Any idea? Thanks!
