[fa.info-mac] Unlocking Caps Lock

This is how you do it for your Mac (I just now did it).  The result is a
non-locking Caps Lock key with a somewhat stronger spring to it.  Of
course, it is still a Caps key.

Read all of this first:

Tools:
	Phillips screwdriver for screws on bottom of the keyboard.
	Solder sucker/wick.
	Soldering iron.
	Small prying tools (jewelers screwdrivers, small knife blade, etc).
	Tweezers/small needlenose pliers.

1) Remove the five screws.  The keyboard should fall into three pieces.

2) GENTLY pry off the Caps Lock keycap.  This takes a little patience.

3) Remove the restoring spring (it will get in the way, I think).

4) Locate the two connections to the Caps Lock key on the back of the PC
   board, and remove all solder from them using wick or sucker.  Be
   careful not to overheat the solder pads, since they can be damaged
   (come loose from the PC board).

5) Pry back the plastic locking clips holding the key in, and remove it.
   (All the keys are clipped into a metal frame.  Removing the metal frame
   is not possible, since all the keys are soldered to the PC board, and
   clipped to the frame.  The clips are located "north" and "south" of the
   key, where the number row is "north" and the space bar "south".)

6) There are four clips holding the bottom of the key on; pry these back,
   and, WHILE HOLDING THE KEY BOTTOM UP, remove the bottom of the key.

7) Two pieces should be ready to fall out; a small piece of PC-board-like
   material (about 7/16 by 3/32 inch, with two notches on one edge and a
   tiny hole in the center), and a tiny piece of wire (a small, beefy
   staple with short legs).  Let them fall out. (It may help to toggle the
   key).

8) Replace the restoring spring, snap the key back into place, resolder
   the two leads, screw the keyboard back together, and replace the key
   cap.  You may wish to experiment with the spring to reduce the key's
   springiness (this can be done with the keyboard assembled, though
   removing the cap is more difficult).
