Figured out how to remap keys in Poseidon except.. when I try to save as defaults, I get "Failed to write config to 'ENV:Sys/poseidon.prefs"

What am I doing wrong?

Try Active Class -> Save from the screenbar menu.

okay, that worked, and now the changed keymap is showing again after a reboot but... no dice.

I tried remapping "scroll lock" and "pause" on my old IBM keyboard to left and right amiga respectively, but they don't seem to actually work.
