If you wish to make a toggle, use this code:

 if(Input.GetKeyDown(KeyCode.LeftArrow)){
 renderer.enabled = !renderer.enabled;
 }

This will set the .enabled variable to the opposite of itself.

The problem with your previous code was that you used Input.GetKeyDown This method is only true for 1 frame and the next frame the script will run the else{} code and overwrite the code done in the previous frame.

You should use Input.GetKey(KeyCode.LeftArrow) instead.

Good luck!

You should use Input.Get$$anonymous$$ey this will be true as long as you hold the specified button.

Also don't use two separate if statements, make it 1. This won't overwrite the other if statement.

 if(Input.Get$$anonymous$$ey($$anonymous$$eyCode.LeftArrow) || Input.Get$$anonymous$$ey($$anonymous$$eyCode.RightArrow)){
  renderer.enabled = false;
 }
 else{
 renderer.enabled = true;
 }

I'm 100% sure this will work.

the || things mean 'or' *
