No Apple software I'm aware of intercepts C-w, or any other control
character for that matter, in any version of osx.  A few control
characters can be used in aqua text widgets for emacs-like navigation,
but only if the widget is selected.  Similarly many applications will
use control in conjunction with mouse clicking, but only if that
application is selected.  

The only keys I can think of that are grabbed are the command/windows
key (for cmd-tab, which is like alt-tab in Windows), some function
keys, and some special purpose keys that appear only on Apple
keyboards (volume control, cd eject).


Otoh there are 3rd-party tools that can definitely be configured to
grab certain control sequences.  For instance VirtualDesktop can be
made to grab C-leftarrow and C-rightarrow for desktop navigation.
Presumably something like this is what's happening here.
