right

bind keys

says). 

    Panagiotis> So, to recap:

    Panagiotis> 1. I think currently there is a documentation bug: "kbd" is 
mentioned in
    Panagiotis> text but not used in the example immediately following it.

yes

    Panagiotis> 2. Other documentation sources (emacs lisp reference manual in 
emacs-29
    Panagiotis> branch) explicitly state that the preferred way to bind keys in 
emacs 29
    Panagiotis> is using "the syntax supported by 'key-valid-p'" and that "[the 
old
    Panagiotis> functions] should not be used in new code." (section 23.13 of 
elisp
    Panagiotis> reference in emacs-29)

yes

    Panagiotis> So, assuming that we want the documentation as a whole to be 
consistent,
    Panagiotis> I see two ways forward: either we eliminate or reduce the 
importance of
    Panagiotis> the old functions in the user manual, or we remove the effective
    Panagiotis> deprecation of the old functions in the emacs lisp reference 
manual and
    Panagiotis> expand on the use of 'kbd', 'global-set-key' and 'define-key'.

    Panagiotis> What do you think?

The syntax accepted by the new functions is that of `kbd', so as long
as that syntax is explained somewhere I guess we can remove references
to `kbd' itself.
