I think I got that address by logging the raw buffers address used while shooting. It's used as fallback, for things like the benchmark module.

Those constants specify the buttons to be masked when CHDK is in ALT mode. For KEYS_MASK0, OR together key constants from group 0 of keymap (see include/kbd_common.h), etc.

@srsa-hu done the file modules; CHDK starts straightaway!
I'm staring at the M100's boot.c and I can't find where you are unlocking the card and enabling the ALT button...

You'll need to implement and override the keyboard task (mykbd_task) for them to work. Note that 1) you don't need the CAM_HAS_JOGDIAL parts for basic operation 2) you won't have control over the shutter button(s) until you implement the PhySw_ReleaseSw stuff. The workaround I use in kbd.c for the shoot/halfshoot states is not very good.
