i'm having a hard time using shaco ult

Pressing "R" moves it as well. Other similar Ults are the same way, and I think LeBlanc is the only one that has to use the keybind to move hers.

if you press r to make the clone move then let go and move yourself then press r and do that really fast you can both move without one obviously being a clone

also i dont think you have to click when moving clone you can just press r and he will go to the cursor
