[Benjamin Klüglein <scheibenkaes@xxxxxxxxxxxxxx>]

That's a good idea! It has to be adapted a bit as we have only two
directions to walk to, but it should solve the missing key event issue.
I saw that the release events are coming properly.

That's coming handy as I wanted to refactor the keyup/keydown handling
anyway, as it's a bit smelly. :-)
I would suggest that I change the key handling together with the general
keyup/keydown handling as it's lying very close together, but I wouldn't
insist on that. :-)

PS: Thanks btw for adding the yaml installation checks. I sometimes forget
that not every user can determine which package is missing from only the
stacktrace. :-) I added you to the Credits file as jezra, if you want to be
mentioned there in a different manner don't hesitate to change it. :-)
