hi. I'm using MacOS 10.6.4

For this OS, command+TAB switches applications on the desktop.  But I wish
to use the command key as "control" for Emacs.

If I change the setting command-key to be "control", I cannot now switch
applications.

Is there anyway to take advantage of both: command+TAB for switching
applications, command=control for Emacs interface?
