(NOTE: Current and future versions of this and any other Advantage 2-related things I post will be at https://github.com/nicholasknight/adv2keyboard)

I received my Advantage 2 today. There's no full manual yet, even though keyboards are apparently arriving (hint, hint, Kinesis). The quick start guide leaves out the "power user mode", and there are some other quirks.

Update: A manual has been posted at http://www.kinesis-ergo.com/advantage2-resources/

It includes a dictionary for the key maps, but I know it leaves at least one possible key undocumented: it does not list f14, but I have successfully mapped my scrollock to f14 regardless.

It also mentions a firmware version (1.0.18) that doesn't seem to be available yet, with a new feature (status report playback speed).

Debugging Redis Keyspace Misses

Simply put, a keyspace "MISS" means some piece of data you tried to retrieve from Redis was not there. This usually means that one of the following things happened:

1. The key expired
2. They key was renamed
3. The key was deleted
4. The key was evicted due to memory pressure
5. The entire database was flushed
6. The key was never actually inserted
