Actually, Vivienne, I have a solution that you can use right away. It'll make data analysis tiny bit more challenging, which I'll explain and offer a suggestion too.
Here's how it works. Instead of using references to text stimuli, you can define a choice response like this:
This creates a choice response that operates in “key_only” mode, which removes the buttons. One option is a single space (" "), and the other is a double space (" ")—though you can make the second option longer if needed, as long as it’s distinct from a single space. In my example, the correct "target" is the double space, but you can easily switch it to the single space for different stimulus conditions.
I’ve tested this, and the result looks perfect - it behaves exactly as you described. It also correctly tracks whether the participant’s response is correct or not, since a single space is distinct from a double space.
The challenge for data analysis is that you’ll need to keep track of what the single space versus double space represents in your output CSV. This can be a bit confusing to remember, but if you recode these values early in your analysis to something more intuitive, it should be manageable. Just be mindful of the process to avoid errors.

"m"
