Tried to map it from Preferences -> Settings -> Keyboard, but the "key" combo box has only "forward delete" but no "delete". My keyboard on the other hand has only "delete" and no "forward delete"!
Is there some other way to do it except from the preferences?
Terminal

Use option key as meta key

Many applications (including bash and tcsh) treat Meta-Delete as "backward delete word."
