git clone https://github.com/stefansaraev/keytable
cd ./keytable
make
# Remap Alt to Win
sudo ./keytable -k 0x700e2=125 --device /dev/input/event13
# Remap Win to Alt
sudo ./keytable -k 0x700e3=56 --device /dev/input/event13

This is useful for if you want Kinto.sh to use the "Apple" keyboard layout instead so that you can remote into macOS with the right keyboard layout, so that you will not need to re-arrange your key layout any on macOS.

The built in laptop keyboards can be remapped as well via setkeycodes

sudo setkeycodes 38 125
sudo setkeycodes e05b 56

On windows you would use Sharpkeys and a file from kinto. https://github.com/rbreaves/kinto/blob/master/windows/WinToMac_AltWin_swap.skl?raw=true

Will need to update this so that this fix gets applied on the USB keyboard always. (disconnects and reconnects causes it to lose the setting)
