Lampz, i'm not sure what you want to see on screenshots - RoExt draws nothing on screen, only changes how RO client behaves in some situations.
As Procabiak said, key remapping is not like autoclicking - it's like moving keys around. For example if you enable mouse buttons remapping for renewal client, when you press middle mouse button RO client will think you pressed F24 on your keyboard instead. It allows you to bind some skill there as you can customize hotkeys in renewal client, but it understands only keyboard keys not mouse buttons.
