 For instance, holding and releasing `LT(2, KC_SPACE)` without hitting another key will result in nothing happening. With this enabled, it will send `KC_SPACE` instead.
 
+For more granular control of this feature, you can add the following to your `config.h`:
+
+```c
+#define RETRO_TAPPING_PER_KEY
+```

+You can then add the following function to your keymap:
+
+```c
+bool get_retro_tapping(uint16_t keycode, keyrecord_t *record) {
+    switch (keycode) {
+        case LT(2, KC_SPACE):
+            return true;
+        default:
+            return false;
+    }
+}
