The special pattern <buffer> or <buffer=N> defines a buffer-local autocommand.
See |autocmd-buflocal|.
+If the `:autocmd` is in Vim9 script then {cmd} will be executed as in Vim9
+script. Thus this depends on where the autocmd is defined, not where it is
+triggered.

Note: The ":autocmd" command can only be followed by another command when the
'|' appears before {cmd}. This works: >
:augroup mine | au! BufRead | augroup END
