Hey Steve,
This is because Apple delights in screwing with you...
Run this in Apple's Script Editor or preferably Script Debugger.
(Note – the commercial version of SD reverts to a freeware "lite" version after a demo period, and this is still waaay more powerful than the ASE.)
tell application "System Preferences"
tell pane "Keyboard"
anchors
end tell
end tell
Note the names of the anchors...
