-    Key events require a mapping function to convert your platform's key values to ImGuiKey's:
+    For adding key events, you're responsible to map your own key codes to ImGuiKey
+    values and pass those as int:
 
-        int map_keycode(int keycode) {
-            // Your mapping logic here...
-        }
-        simgui_add_key_event(map_keycode, keycode, true);
+        simgui_add_key_event(imgui_key, true);
 
     Take note that modifiers (shift, ctrl, etc.) must be updated manually.
