I've asked this question before but did not get the answer I wanted.
What I want to be able to do is to be able to turn off Caps Lock either
by using the Shift key or by using the Caps Lock key: the way a
typewriter used to work.

It's possible to use a DWORD to make Shift turn off Caps Lock, but it's
then no longer possible to turn it off with the Caps Lock key:

> In the Registry key HKEY_CURRENT_USER\ Keyboard Layout, create a DWORD value named Attributes, if it isn't already present. Double-click on it, then choose Hexadecimal, and set its value to 00010000. Now, when you press and release the Shift key while the Caps Lock is active, Caps Lock will turn off.

I wonder if it would be possible to change the value of the DWORD so
that I could turn off Caps Lock using either key. I'm reluctant to
experiment since I'm not sure I could recover if I lost keyboard
functionality.

Any help would be appreciated.
