Scroll shared prototype with keyboard
When viewing a prototype, a user can scroll between views using the left and right keyboard arrow keys but cannot scroll up or down on the current prototype with the keyboard. Some viewers have been unable to scroll with their mouse. Without a visible scrollbar they have been left only seeing what's above the fold line.
On Mac I've discovered that pressing fn+arrow up/down will sort of page you down, but it's not smooth and not intuitive. Simply using arrow keys as you would using a browser (or something close) would be ideal.
2. Why is this valuable to you?
I've had numerous viewers report they cannot see what's below the fold because they cannot get the "scroll" to work and are stuck only viewing above the fold.
