No, you can't do that with the KNFB reader, and in any event, attempting to
use the volume buttons is a poor practice because there is a bigger chance
you'll skew the phone and get a poorer image.
Using the volume controls if you have the camera set to where it takes
several frames does mitigate the problem, but with the KNFB reader, you have
to double or split-tap the left side of the screen for a pic and the
right-side for the field-of-view report. Split tapping is preferrable to
double-tapping for the same reason as not using the volume control.
