Windows annoyance finally useful?

I remember back in the days my gaming, when messing with the key controls I made the mistake of assigning somehting to the shift key.  Hit it 5 times in a row and bam, game gone and windows me begging me to start Sticky Keys.

Now, in the age that our technical engineering has gone beyond our physical engineering, keyboards are now becoming deal breakers.  MicroPCtalk has been playing with the new UX and discovered that an old useless feature is now useful.  Amazing.
