My Unicomp keyboard is dated 3/27/2014, and its single-width keys are the two-part style.
So are the wide keys on the bottom row. Other wide keys, including Caps Lock, are
single-part. I swapped left Ctrl and Caps lock on my keyboard using custom keys that I
ordered separately plus a Windows registry hack.
