In XEmacs, both descriptions are incorrect.  "Shifted motion selects"
is a property of the key, not of the command nor of its name.

XEmacs has used a variable containing a list of key names that might
have this behavior for ten years with no apparent ill-effects.  And it
similarly has been hard-coded to the shift key for ten years with no
apparent ill-effects.
