Thanks alextootchie. It worked. But it requires that I use the hardware keyboard to press CTRL + F then close the keyboard to get to the virtual one. Is there a simpler way?

And when Evince searches for or finds a term or phrase, there's a small note on the lower right of the screen that says "xx% remaining t..." while searching, then "2 found on p..." How do you see what the whole message says? I can't click it or scroll the screen to see it.
