[Thinkpad] T40: Right Ctrl+ Left Arrow in XP

[Doug Simmons]

I've just gotten my new T40 with XP (previously had T22 with W2k) and am 
getting adjusted to the new OS.

I'm not sure if it is a function of the TP or XP, but one of my favorite 
shortcut key combinations in Word now has changed.  The subject combination 
(Right Ctrl + Left Arrow key) activates the volume controls, muting the 
volume.  It is the same in all applications that I used the combination to 
move one word left.  I found nothing in the help about the combination in 
the XP help and saw nothing either in the ThinkPad configuration help.  The 
Left Ctrl + Left arrow key does move one word left as it should and both 
the left and right Ctrl + Right Arrow key moves one word to the right.

Does anyone know which changed the function, TP or XP?  And more 
importantly can it be changed back to what I'm accustomed to?

Thanks,

Doug
