+ *
+ * 2. direct_key_map is the key code map for the direct keys, if rotary
+ * encoder(s) are enabled, direct key 0/1(2/3) will be ignored
+ *
+ * 3. rotary can be either interpreted as a relative input event (e.g.
+ * REL_WHEEL/REL_HWHEEL) or specific keys (e.g. UP/DOWN/LEFT/RIGHT)
+ *
+ * 4. matrix key and direct key will use the same debounce_interval by
+ * default, which should be sufficient in most cases
