Re: Meta and Alt confusion in the manual

[Richard Stallman]

        determine from the partial name.  (If your window manager defines
        `M-<TAB>' to switch windows, you can type `<ESC> <TAB>' or `C-M-i'.)

    The window manager of course does not use M-<TAB>. It uses Alt-<TAB>. 
    Meta is Emacs specific and could be on another keyboard key than Alt.

    I think this should be corrected to avoid confusion.

I am not sure the existing text is wrong, but if you suggest a change,
I will think about it.
