Rebind your use key. Normally, it's E, but you can change it by going to the pause menu and then going to 'Options', and then try to find the 'Interact' key or 'Use' key or whatever and double-click it. Then type 'J' and then click 'Apply' on the bottom-right corner of the options window. Boom, you just reconfigured one of your keys.

well you can but it will change your Use key easy enough you go into the console just type Bind J +use



and if that doesnt work do alias j +use then Bind j j
