# Caps Word
|
|
|
|
It is often useful to type a single word in all capitals, for instance
|
|
abbreviations like "QMK", or in code, identifiers like `KC_SPC`. "Caps Word" is
|
|
a modern alternative to Caps Lock:
|
|
|
|
* Letters are capitalized while active, and Caps Word automatically disables
|
|
itself at the end of the word. That is, it stops by default once a space or
|
|
any key other than `KC_A`--`KC_Z`, `KC_0`--`KC_9`, `KC_MINS`, `KC_UNDS`,
|
|
`KC_DELETE`, or `KC_BACKSPACE` is pressed. Caps Word also disables itself if
|
|
the keyboard is idle for 5 seconds. This is configurable, see below.
|
|
|
|
* To avoid requiring a dedicated key for Caps Word, there is an option
|
|
(`BOTH_SHIFTS_TURNS_ON_CAPS_WORD`) to activate Caps Word by simultaneously
|
|
pressing both shift keys. See below for other options.
|
|
|
|
* The implementation does not use the Caps Lock (`KC_CAPS`) keycode. Caps Word
|
|
works even if you're remapping Caps Lock at the OS level to Ctrl or something
|
|
else, as Emacs and Vim users often do. As a consequence, Caps Word does not
|
|
follow the typical Caps Lock behaviour and may thus act in potentially
|
|
unexpected ways, especially when using an *OS* keyboard layout other than US
|
|
or UK. For example, Dvorak's <kbd>, <</kbd> key (`DV_COMM` aka `KC_W`) will
|
|
get shifted because Caps Word interprets that keycode as the letter 'W' by
|
|
default, the Spanish <kbd>Ñ</kbd> key (`ES_NTIL` aka `KC_SCLN`) will not get
|
|
capitalized because Caps Word interprets it as the semicolon ';' punctuation
|
|
character, and the US hyphen key (`KC_MINS`), while unaffected by Caps Lock,
|
|
is shifted by Caps Word. However, this is not really a problem because you can
|
|
[configure which keys should Caps Word
|
|
shift](#configure-which-keys-are-word-breaking).
|
|
|
|
|
|
## How do I enable Caps Word :id=how-do-i-enable-caps-word
|
|
|
|
In your `rules.mk`, add:
|
|
|
|
```make
|
|
CAPS_WORD_ENABLE = yes
|
|
```
|
|
|
|
Next, use one the following methods to activate Caps Word:
|
|
|
|
* **Activate by pressing a key**: Use the `CAPS_WORD` keycode (short
|
|
alias `CAPSWRD`) in your keymap.
|
|
|
|
* **Activate by pressing Left Shift + Right Shift**: Add `#define
|
|
BOTH_SHIFTS_TURNS_ON_CAPS_WORD` to config.h. You may also need to disable or
|
|
reconfigure Command, details below. Then, simultaneously pressing both left
|
|
and right shifts turns on Caps Word. This method works with the plain
|
|
`KC_LSFT` and `KC_RSFT` keycodes as well as one-shot shifts and Space Cadet
|
|
shifts. If your shift keys are mod-taps, hold both shift mod-tap keys until
|
|
the tapping term, then release them.
|
|
|
|
* **Activate by double tapping Left Shift**: Add `#define
|
|
DOUBLE_TAP_SHIFT_TURNS_ON_CAPS_WORD` config.h. Then, double tapping Left Shift
|
|
turns on Caps Word. This method works with `KC_LSFT` or one-shot Left Shift
|
|
`OSM(MOD_LSFT)`. To count as a double tap, the maximum time in milliseconds
|
|
between taps is `TAPPING_TERM`, or if using `TAPPING_TERM_PER_KEY`, the time
|
|
returned by `get_tapping_term()` for the shift keycode being tapped.
|
|
|
|
* **Custom activation**: You can activate Caps Word from code by calling
|
|
`caps_word_on()`. This may be used to activate Caps Word through [a
|
|
combo](feature_combo.md) or [tap dance](feature_tap_dance.md) or any means
|
|
you like.
|
|
|
|
### Troubleshooting: Command :id=troubleshooting-command
|
|
|
|
When using `BOTH_SHIFTS_TURNS_ON_CAPS_WORD`, you might see a compile message
|
|
**"BOTH_SHIFTS_TURNS_ON_CAPS_WORD and Command should not be enabled at the same
|
|
time, since both use the Left Shift + Right Shift key combination."**
|
|
|
|
Many keyboards enable the [Command feature](feature_command.md), which by
|
|
default is also activated using the Left Shift + Right Shift key combination. To
|
|
fix this conflict, please disable Command by adding in rules.mk:
|
|
|
|
```make
|
|
COMMAND_ENABLE = no
|
|
```
|
|
|
|
Or configure Command to use another key combination like Left Ctrl + Right Ctrl
|
|
by defining `IS_COMMAND()` in config.h:
|
|
|
|
```c
|
|
// Activate Command with Left Ctrl + Right Ctrl.
|
|
#define IS_COMMAND() (get_mods() == MOD_MASK_CTRL)
|
|
```
|
|
|
|
|
|
## Customizing Caps Word :id=customizing-caps-word
|
|
|
|
### Idle timeout :id=idle-timeout
|
|
|
|
Caps Word turns off automatically if no keys are pressed for
|
|
`CAPS_WORD_IDLE_TIMEOUT` milliseconds. The default is 5000 (5 seconds).
|
|
Configure the timeout duration in config.h, for instance
|
|
|
|
```c
|
|
#define CAPS_WORD_IDLE_TIMEOUT 3000 // 3 seconds.
|
|
```
|
|
|
|
Setting `CAPS_WORD_IDLE_TIMEOUT` to 0 configures Caps Word to never time out.
|
|
Caps Word then remains active indefinitely until a word breaking key is pressed.
|
|
|
|
|
|
### Functions :id=functions
|
|
|
|
Functions to manipulate Caps Word:
|
|
|
|
| Function | Description |
|
|
|-------------------------|------------------------------------------------|
|
|
| `caps_word_on()` | Turns Caps Word on. |
|
|
| `caps_word_off()` | Turns Caps Word off. |
|
|
| `caps_word_toggle()` | Toggles Caps Word. |
|
|
| `is_caps_word_on()` | Returns true if Caps Word is currently on. |
|
|
|
|
|
|
### Configure which keys are "word breaking" :id=configure-which-keys-are-word-breaking
|
|
|
|
You can define the `caps_word_press_user(uint16_t keycode)` callback to
|
|
configure which keys should be shifted and which keys are considered "word
|
|
breaking" and stop Caps Word.
|
|
|
|
The callback is called on every key press while Caps Word is active. When the
|
|
key should be shifted (that is, a letter key), the callback should call
|
|
`add_weak_mods(MOD_BIT(KC_LSFT))` to shift the key. Returning true continues the
|
|
current "word," while returning false is "word breaking" and deactivates Caps
|
|
Word. The default callback is
|
|
|
|
```c
|
|
bool caps_word_press_user(uint16_t keycode) {
|
|
switch (keycode) {
|
|
// Keycodes that continue Caps Word, with shift applied.
|
|
case KC_A ... KC_Z:
|
|
case KC_MINS:
|
|
add_weak_mods(MOD_BIT(KC_LSFT)); // Apply shift to next key.
|
|
return true;
|
|
|
|
// Keycodes that continue Caps Word, without shifting.
|
|
case KC_1 ... KC_0:
|
|
case KC_BSPC:
|
|
case KC_DEL:
|
|
case KC_UNDS:
|
|
return true;
|
|
|
|
default:
|
|
return false; // Deactivate Caps Word.
|
|
}
|
|
}
|
|
```
|
|
|
|
|
|
### Representing Caps Word state :id=representing-caps-word-state
|
|
|
|
Define `caps_word_set_user(bool active)` to get callbacks when Caps Word turns
|
|
on or off. This is useful to represent the current Caps Word state, e.g. by
|
|
setting an LED or playing a sound. In your keymap, define
|
|
|
|
```c
|
|
void caps_word_set_user(bool active) {
|
|
if (active) {
|
|
// Do something when Caps Word activates.
|
|
} else {
|
|
// Do something when Caps Word deactivates.
|
|
}
|
|
}
|
|
```
