If you want to see more of what has been added, see the NEWS file by
typing C-h n. Unfortunately, this file (for Emacs 28) is large (4000
lines) and the new function above is not mentioned until line 3540.
A new feature that was added Emacs 28 is the ‘shortdoc-display-group’.
Type:
M-x shortdoc-display-group <TAB>
to see a list of the groups for which shortdoc help is available. These
are only a subset of the functions that are available in Emacs.
Type:
M-x shortdoc-display-group <RET>
and then type "buffer" (no quotes) in response to the prompt:
Show summary for functions in: buffer
This will then list brief help/descriptions for many buffer-related
functions in a ‘shortdoc’ buffer, including ‘replace-string-in-region’.
