I tried this in the latest snapshot, 26.1 Snapshot 5, but the issue persists. It's possible this is because I have an Aceline keyboard. However, I can't provide a video of what's happening because I don't know how to show that I'm pressing the FN key and trying to assign it an action, and no website shows the FN key being pressed. Could you please tell me what method you used when you demonstrated that you were able to assign the jump key to the FN key?
