* @file custom_shift_keys.h |
||||
* @brief Custom shift keys: customize what keycode is produced when shifted. |
||||
* |
||||
* Overview |
||||
* -------- |
||||
* |
||||
* This library implements custom shift keys, keys where you can customize |
||||
* what keycode is produced when shifted. |
||||
* |
||||
* Step 1: In your keymap.c, define a table of custom shift keys like |
||||
* |
||||
* #include "features/custom_shift_keys.h" |
||||
* |
||||
* const custom_shift_key_t custom_shift_keys[] = { |
||||
* {KC_DOT , KC_QUES}, // Shift . is ?
|
||||
* {KC_COMM, KC_EXLM}, // Shift , is !
|
||||
* {KC_MINS, KC_EQL }, // Shift - is =
|
||||
* {KC_COLN, KC_SCLN}, // Shift : is ;
|
||||
* }; |
||||
* |
||||
* Each row defines one key. The first field is the keycode as it appears in |
||||
* your layout and determines what is typed normally. The second entry is what |
||||
* you want the key to type when shifted. |
||||
* |
||||
* Step 2: Handle custom shift keys from your `process_record_user` function as |
||||
* |
||||
* bool process_record_user(uint16_t keycode, keyrecord_t* record) { |
||||
* if (!process_custom_shift_keys(keycode, record)) { return false; } |
||||
* // Your macros ...
|
||||
* |
||||
* return true; |
||||
* } |
||||
* |
||||
* Step 3: add `features/custom_shift_keys.c` to your rules.mk as |
||||
* |
||||
* SRC += features/custom_shift_keys.c |
||||
* |
||||
* |
||||
* For full documentation, see |
||||
* <https://getreuer.info/posts/keyboards/custom-shift-keys>
