How do I do user macros in Anzio Lite?

User macros are created and edited using AnzioWin. While Anzio Lite does not support remapping itself, if these are simple macros (with no non-Anzio Lite commands), Anzio Lite can use macros set up by AnzioWin. So you would need at least one copy of AnzioWin to do the macros and then distribute the modified key file containing the macros to the Anzio Lite users.
