Re: USB keyboard occasional key stuck

I noticed your examples are both fn combos. I'm seeing something like
this and it seems specifically related to the fn key. Reproducible on a
Macbook (3,1) and a Lenovo Yoga 13. Sequence is simple:

Press key
Press fn
Release key
Release fn

The key will be 'stuck' until you press another key. It seems to only
apply to keys that are part of a fn combo

Fn is handled by the embedded controller (H8 as per Intel reference
design in case of Macbook or Thinkpad) which has its own closed
firmware which is rarely perfectly bug-free.
