I disagree.  Screen changes happen all the time at random moments. I 
would be very upset if I was in the middle of reading the time provided 
by brltty and it gets pulled away when I'm in halfway through it.

Detecting key presses is certainly a good signal to use for discarding 
messages. In the absence of a keyboard table then a new key binding for 
the purpose of discarding messages in a message context could be 
defined. In such a context the up and down navigation keys could be 
used.
