FBReader's find is a long press of number 8. See the 1st two attached scans (at 100 dpi, so lower resolution than the screen).
The 2nd two scans show dictionary lookup in CR3 (press key 2 or use the menu). It does not use the on-screen keyboard but rather a number per 3 characters mapping to the words on the screen. I did not have any dictionaries installed though.
