* @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>
