recently acquired a tatung branded sun 5 (?) board, successfully restored and converted it with this firmware.
it has a big beeper and screams everytime i connect. so my guess would be it is working like the other sun keyboards and is potentionally able to output beeps/clicks with each keypress.

to use this feature i would need to use the tmk "magic" key combo, which in this case would be both shift, both alt or both meta keys + a single extra key. it seems the matrix isnt able to do that.

my question here is, is there any way to remap "magic" key combos, or even to map a key to a single hexcode?
beside wiring up converters and putting the *.hex from the online editor on to the chip my knowledge is very limited.

also off topic: if anyone has any infos on the board or the system it came with it would be much appreciated. couldnt find any infos or pictures at all. its a forward fdw-107a

pic of board attached for beauty bonus

You have to edit these lines and compile firmware to change the command.

thanks,
remapping combo to two different mods (shift/alt) helped and it works now.

--- Code: ---#define IS_COMMAND() ( \
    keyboard_report->mods == (MOD_BIT(KC_LSHIFT) | MOD_BIT(KC_LALT)) \
)
--- End code ---
thanks to my friend kelvinhall05 for figuring out with me and the compile.
