Dave, how do I search for these revision indicators in git log?
It looks like "g08c6e86a" doesn't appear anywhere.

Lars: I used to see occassionally ignored navigation key presses.  In
other words, I would press a triple-action key, but the braille on my
display would not change.  Pressing it again usually cleared up the
problem.

I am now running with the absolutely latest code, and have not seen any
problem sofar.

How old is your build of BRLTTY, actually.

Most navigation keys only act upon release, but I guess you know that?

As said, I have seen keypress problems with this particular device
during development of 5.X as well.  Please make sure you run the latest
code, so that we can give this issue a closer look before the release.
