No, M-DEL is the canonical key.  Anthing defined via function-key-map is

Ah, thanks. That means my latest patch for the tutorial is wrong AFAICS now - so please do not install that - yet.

I had to consult Webster to see what canonical really means ....

Now let me see if I understand this... - here is then another question around this:

As I understand it now the preferable way to define a key is (of course) always to use a canonical representation. Maybe it even can not be done in any other way?

But then I do not understand the use of M-backspace. In pc-mode.el M-backspace is used for keybinding. Works ok on w32 and I guess on other platforms too? But backward-kill-word is not bound to M-backspace directly on w32, but instead through function-key-map. Why is it so? Where is backward-kill-word on other systems? What does C-h w give? What does M-backspace do on other systems?
