since the keycode for a tap dance process gets process only after the
TAPPING_TERM timeout, you really only have ONESHOT_TIMEOUT -
TAPPING_TERM time to tap or double tap on the key. This fix save the
oneshot_mods into the action.state structure and applies the mods with
the keycode when it's registered. It also unregisters the mod when the
the tap dance process gets reset.
Scenario:
Locking the KC_LSHIFT, and then using a tap dance key that registers a
S(KC_9) will unregister the KC_LSHIFT.
The tap dance or any keycode that is registered should not have the
side effect of cancelling a locked moditifier. We should be using a
similar logic as the TMK codes in tmk_core/comman/action.c:158.
In register_code16 and unregister_code16 we call register_code and
unregister_code twice, once for the mods and once for the keycode.
The (un)register_code have many check to see that keycode we have sent
however because we know that we are sending it a mods key, why not
just skip all of it and call (un)register_mods instead. This will skip
alot of checks and should speedup the loop a little.
the quantum matrix codes where not being initialized or/and called
so no feature of the quantum firmware could be used. These codes have
been added and now we can enjoy the quantum firmware goodness.
Since we can't read the real_mods and oneshot_mods static variable
directly within the update_user_visualizer_state
function (Threading and serial link). We are know storing the mods
states in the visualizer_keyboard_status_t structure. We can now
display the status of the modifier keys on the LCD display.
