How Can You Control Shaco's Clone

You can press R again, or use the keybind you set (you'll need the keybind for Leblanc's clone)

Press R, right click where you want the clone to go\what you want it to attack, and pray that it actually follows the order. Shaco's clone has been needing tweaks for the entirety of its existence, yet Riot is content to ignore it. You can also try alt+clicking, but don't forget the praying part.

yeah, you control shaco's clone, Morde's ghost, and Annie's Tibbers by pressing R and right clicking where you want it to go/attack

Actually just press r after u used it and it follows no need to right click afterwards.

you control "ult" clones by directing it with r - shaco, morde, yorick, annie.

you control leblanc's clone by pressing alt + leftclick. you can also control ult clones this way, but pressing one button seems easier.

It's literally in the tooltip
