A user who hovers their hands and/or moves them laterally may prefer the lower-left control, as combined with movement of the palm, it offers a more open access to the leftmost keys. It also allows control-and-shift operations to be performed without curling the little finger underneath. Some workarounds include using little-finger-shift and ring-finger-control or thumb-control presses. Such change to the point of origin does reduce the useful radius of the first four fingers across the keyboard, yet may be more ergonomic for the hand.
