It's called "opt" in mac-speak.
No, there doesn't seem to be a defined symbol. The symbols are defined in:

https://git.gnome.org/browse/gtk+/tree/gdk/quartz/gdkkeys-quartz.c
https://git.gnome.org/browse/gtk+/tree/gdk/gdkkeysyms.h
https://git.gnome.org/browse/gtk+/tree/gdk/gdkkeyuni.c

You should be able to just trap is as <alt>'w' as an accelerator or binding, but recognize that your 
non-English users may  consider it a bug if it prevents them from actually typing that in a text field. If 
you're trying to use it for something else, maybe a bit more explanation will help find a solution for you.
