Someone is too stupid to have a computer
Although, a little might be said in their defense:
some old-timers grew up with typewriters, and for those, to turn Shift-lock off you just pressed shift.
Japanese (and maybe other Asian) keyboards require you to press shift and caps lock together to toggle caps lock. I had a frustrating time until I figured this out, and once had to type emails holding the shift key down to force the machine back into lower case.
