Requires virtser; Allows QMK to speak the TX BOlt protocol used by stenography machines and software (such as Plover). The upside is that Plover can be configured to listen only to TX Bolt allow the keyboard to switch layers without need to enable/disable the Plover software, or to have a second non-Steno keyboard work concurrently.
Instead of having all sendstring keycode mappings in the main quantum.c
file, give each one its own file in keymap_extras that can be #included
in a user's keymap. If one is included, it will define the appropriate
lookup tables and overwrite the weak definitions in quantum.c.
(Including more than one sendstring definition will fail at compile
time.)

Refactor new-ish JIS_KEYCODE send_string implementation with existing

an option MIDI_ENABLE_STRICT to be strict about keycode use (which also
reduces memory footprint at runtime)
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.
Define a default TAPPING_TERM in quantum.c, for keyboards that do not
have it set. Fixes the CI failure.

When one holds a Space Cadet shift, to have it act as a shift, so that
mouse behaviour changes, when released without any other key pressed, it
still registers a paren. To remedy this, add a hold timeout: if the key
is held longer than TAPPING_TERM, it will not register the parens.
Fixes#884, with the side-effect of not being able to have parens
trigger the OS-side repeat anymore.

These functions register not only the 8bit keycode, but the modifiers
too. It doesn't handle the full range of the upper 8bits, just the mods,
but that's a good start.
Changed the tap-dance pair functions to use these, so one can do:
`ACTION_TAP_DANCE_DOUBLE (KC_COLN, KC_SCLN)`
...and that will do the right thing.

RGB_SAD (decrease saturation)
RGB_VAI (increase brightness)

Allows you to press RSHIFT to cancel the insertion of a "(" when holding down LSHIFT. Alternatively, allows you to press LSHIFT to cancel the insertion of a ")" when holding down RSHIFT. This change enables you to renege from outputting a character should you press a shift key erroneously.

* quantum: Add a tap dance feature (#451)
* quantum: Add a tap dance feature
With this feature one can specify keys that behave differently, based on
the amount of times they have been tapped, and when interrupted, they
get handled before the interrupter.
To make it clear how this is different from `ACTION_FUNCTION_TAP`, lets
explore a certain setup! We want one key to send `Space` on single tap,
but `Enter` on double-tap.
With `ACTION_FUNCTION_TAP`, it is quite a rain-dance to set this up, and
has the problem that when the sequence is interrupted, the interrupting
key will be send first. Thus, `SPC a` will result in `a SPC` being sent,
if they are typed within `TAPPING_TERM`. With the tap dance feature,
that'll come out as `SPC a`, correctly.
The implementation hooks into two parts of the system, to achieve this:
into `process_record_quantum()`, and the matrix scan. We need the latter
to be able to time out a tap sequence even when a key is not being
pressed, so `SPC` alone will time out and register after `TAPPING_TERM`
time.
But lets start with how to use it, first!
First, you will need `TAP_DANCE_ENABLE=yes` in your `Makefile`, because
the feature is disabled by default. This adds a little less than 1k to
the firmware size. Next, you will want to define some tap-dance keys,
which is easiest to do with the `TD()` macro, that - similar to `F()`,
takes a number, which will later be used as an index into the
`tap_dance_actions` array.
This array specifies what actions shall be taken when a tap-dance key is
in action. Currently, there are two possible options:
* `ACTION_TAP_DANCE_DOUBLE(kc1, kc2)`: Sends the `kc1` keycode when
tapped once, `kc2` otherwise.
* `ACTION_TAP_DANCE_FN(fn)`: Calls the specified function - defined in
the user keymap - with the current state of the tap-dance action.
The first option is enough for a lot of cases, that just want dual
roles. For example, `ACTION_TAP_DANCE(KC_SPC, KC_ENT)` will result in
`Space` being sent on single-tap, `Enter` otherwise.
And that's the bulk of it!
Do note, however, that this implementation does have some consequences:
keys do not register until either they reach the tapping ceiling, or
they time out. This means that if you hold the key, nothing happens, no
repeat, no nothing. It is possible to detect held state, and register an
action then too, but that's not implemented yet. Keys also unregister
immediately after being registered, so you can't even hold the second
tap. This is intentional, to be consistent.
And now, on to the explanation of how it works!
The main entry point is `process_tap_dance()`, called from
`process_record_quantum()`, which is run for every keypress, and our
handler gets to run early. This function checks whether the key pressed
is a tap-dance key. If it is not, and a tap-dance was in action, we
handle that first, and enqueue the newly pressed key. If it is a
tap-dance key, then we check if it is the same as the already active
one (if there's one active, that is). If it is not, we fire off the old
one first, then register the new one. If it was the same, we increment
the counter and the timer.
This means that you have `TAPPING_TERM` time to tap the key again, you
do not have to input all the taps within that timeframe. This allows for
longer tap counts, with minimal impact on responsiveness.
Our next stop is `matrix_scan_tap_dance()`. This handles the timeout of
tap-dance keys.
For the sake of flexibility, tap-dance actions can be either a pair of
keycodes, or a user function. The latter allows one to handle higher tap
counts, or do extra things, like blink the LEDs, fiddle with the
backlighting, and so on. This is accomplished by using an union, and
some clever macros.
In the end, lets see a full example!
```c
enum {
CT_SE = 0,
CT_CLN,
CT_EGG
};
/* Have the above three on the keymap, TD(CT_SE), etc... */
void dance_cln (qk_tap_dance_state_t *state) {
if (state->count == 1) {
register_code (KC_RSFT);
register_code (KC_SCLN);
unregister_code (KC_SCLN);
unregister_code (KC_RSFT);
} else {
register_code (KC_SCLN);
unregister_code (KC_SCLN);
reset_tap_dance (state);
}
}
void dance_egg (qk_tap_dance_state_t *state) {
if (state->count >= 100) {
SEND_STRING ("Safety dance!");
reset_tap_dance (state);
}
}
const qk_tap_dance_action_t tap_dance_actions[] = {
[CT_SE] = ACTION_TAP_DANCE_DOUBLE (KC_SPC, KC_ENT)
,[CT_CLN] = ACTION_TAP_DANCE_FN (dance_cln)
,[CT_EGG] = ACTION_TAP_DANCE_FN (dance_egg)
};
```

set the target OS method in your keymap.c: void matrix_init_user() {
set_unicode_mode(UC_OSX); } you can then switch when you want with:
set_unicode_mode(UC_OSX); set_unicode_mode(UC_LNX);
set_unicode_mode(UC_WIN);
put some unicode codes in your keymap like so: UC(0x0061)
I did change the bit mask in quantum/keymap_common.c and .h
