/**
 * @file custom_shift_keys.h
 * @brief Custom Shift Keys community module: customize how keys shift.
 *
 * This library implements custom shift keys, keys where you can customize what
 * keycode is produced when shifted. In your keymap.c, define a table of custom
 * shift keys like
 *
 *     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.
 *
 *
 * For full documentation, see
 * <https://getreuer.info/posts/keyboards/custom-shift-keys>
