If I open a search window in the epub viewer, I can't use the arrow keys to switch from one search result to the next.

I seem to have to use the mouse.

When I used the arrow keys to try to switch, the viewer "smooth" scrolls down. I can't find a setting to turn off smooth scrolling. I found a setting to speed it up, and figured if it's too fast to see it might not give me motion sickness, but that setting doesn't seem to work.
