more_space_toggle = !more_space_toggle; will toggle what the boolean is storing as ! is the logical NOT operator. So if it currently stores false, it will toggle to true, and vice versa.

! is logical NOT operator. Use this to reverse the logical state of its operand.

!true==false

or

!false==ture
