Mod shift?

[nimishgautam]

Yeah, when I tested it with my keyboard, it worked fine if you hold down 2 keys that send KC_LSFT and KC_RSFT respectfully but it did NOT work when the keys send something like MT(MOD_LSFT, ...) , MT(MOD_RSFT, ...) , So, it seems to work for the KC shifts but not the MOD shifts. Not sure if there's a better way to word that.

Aah, okay, this is due to mod tap using weak mods, and caps words not checking weak mods. That ... is actually a simple fix.

qmk_firmware/quantum/process_keycode/process_caps_word.c

Lines 26 to 28 in 245f00b

	const uint8_t mods = get_mods() | get_oneshot_mods();
	#else
	const uint8_t mods = get_mods();

Changing that would allow for weak mods to be checked. However, it has the caveat of shifted keycodes (eg LSFT(kc)) will also be able to trigger it.
