I have my special action key set to C. So that means if I use C on Fractal 100, I get to do the magical jump thingy. Sometimes when you are riding a mount, you get the option to press C to do special actions such as sniff for hidden enemies. This does not work for me. I can spam C all I want and nothing happens. I have to click it with my mouse. I have C set to use that skill in my options so that's not the reason it doesn't work. I think this is just a bug and hopefully it can be fixed!
