Layer Opacity Keyboard Shortcut

There isn't such a shortcut unfortunately, and while it might be possible to make new shortcuts via the .json config. there isn't a action name defined for increasing and decreasing layer opacity.

Thanks for the response, it's a shame though.  I'd love to see more access to pyxel's preferences and actions via shortcut in the next release.  I would think that adding shortcuts to things like toggling layer visibility, adjusting transparency, etc wouldn't be difficult in the future.
