Left-shift Memes

Left side of keyboard: essential daily tools. Right side: those weird cousins you see at family reunions once every 5 years. The right Shift key might as well be in the Witness Protection Program considering how rarely anyone acknowledges its existence. I've been coding for 15 years and still can't confirm if Right Ctrl actually does anything or if it's just a placebo button installed by keyboard manufacturers to maintain symmetry.
