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

'Keyboard control' command is configured in config.h, you cannot remap in Keymap Editor.

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: [Select]

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