I was running a user test using a figma prototype on UserTesting.com (so I couldn’t interact with the user). In their video, the user was using an on-screen keyboard as their main navigation tool. They seemed to have a mouse, but limited physical ability to use the mouse comfortably. While on the prototype, the user kept trying to use the pg up and pg down functions on the keyboard, as this was much easier for them to use than a mouse, but prototypes - to my knowledge and experience - don’t recognize these keys, and therefor the user was not able to scroll that way.
Would it be possible to add the ability to use pg up and down keys to scrollable prototypes to make user testing and prototypes in general more accessible to users who don’t/can’t use computer mice?
