gnus-Subject-isearch-article).
gnus-Subject-search-article-forward). If regexp is empty,
the last regexp used is used again.
gnus-Subject-search-article-backward). If regexp is empty,
the last regexp used is used again.
gnus-Subject-execute-command). If
field is empty, the entire article is searched for.
The command s (gnus-Subject-isearch-article) does an
incremental search on the current article. The commands M-s and
M-S (gnus-Subject-search-article-forward and
gnus-Subject-search-article-backward) search for articles
containing a match for regexp. The search starts from the current point
of the current article.
The command & (gnus-Subject-execute-command)
interactively reads the field name of article headers, regexp, and a
valid command key sequence. It then searches for articles having a
field that contains a match for the regexp, and then executes the
command specified by the key sequence on them.
