Thought listing question

[plin]

[edited by moderator]
In my questionnaire I want subjects to list their thoughts up to 8 items. At the same time, I allow them to only list 3 item if they don't have any other thoughts. I know I can inform my subjects that they can always end the thought listing by using the ESC key. However, I am afraid that my subjects will avoid answering other thought listing questions after they know the function of the ESC key. So, I am wondering if I could create a skip (e.g., go to next question) to inform subjects (who have answered at least 3 items) that they can go to the next question if they don't have any other thoughts.
Appreciate any reply!
