Run-native under Linux: lots of buttons don’t work, and some undocumented ones do
According to [the documentation](https://wasm4.org/docs/guides/multiplayer#local-multiplayer), there should be a full set of keys for the first three players on a single keyboard. However, using `w4 run-native` on Linux, key input seems to violate the documentation in the following ways:
* Dot and comma don’t do anything (they should be player 1 X and Z).
* None of the numpad keys, which are supposed to be for player 3, do anything.
* W, Y, J, and V, despite not being documented as doing anything, are player 1 Z.
* K, C, and spacebar, despite not being documented as doing anything, are player 1 X.

Also, according to [this page](https://wasm4.org/docs/reference/hotkeys), there should be a bunch of hotkeys that do things in the emulator. None of them appear to do anything.

This is all tested with version 2.5.4, which was the version I got by downloading the Linux ZIP file [here](https://wasm4.org/docs/getting-started/setup). I’m using an ordinary QWERTY keyboard (albeit one with NKRO), and Xorg.
