As you can see, the first bot is Auto-Clicker. The key I set for my maple story hacks MSPro is F12, as highlighted. It means that inside the game, when I press F12, the autoclick rf online would start. Pressing F12 again would stop the Auto-Clicker. You can select the keys by pressing on the drop down menu of each key and selecting your desired keys As you would have noticed, there is a second set of keys beside the first set, as shown in red:

That is the usage key. That key would be what the function (or bot) would press inside the game. For example, the third function, Auto-Loot, I set F9 as the activation key, which means that when i press F9 inside the game, the Auto-Loot Function would maple story mesos start. The second key for the function,for me, i set as Z. Which means, inside the game, when I start the Auto-Loot, it would keep pressing Z. A third part to the MSPro is the HP/MP slider bar, as indicated:
