Examples:
- Visit https://chatgpt.com/, focus the textbox, if it isn’t focused already, press Shift+Tab twice to focus the “Log in” button, and press Enter. Now, the textbox is erroeously focused again, and you’re not taken to the log-in page.
- In an existing AI chat, edit one of your messages by clicking its pen icon, press Tab to focus the “Cancel” button, and press Enter. This simply focuses the default textbox at the bottom of the viewport, while the edit textbox is still there.
In each case, if you press Space instead of Enter, it works.
