However, I think this is exactly what I need -- thanks, Alan, for the first try! Consider this table: foo bar foo=bar bar-foo baz baz=baz baz-foo=baz I would like to make all lines invisable *and* intangible which don't contain a `='. Otherwise interactive search-and-replace would try to modify invisible text. At least this is my conclusion of your explanations. Werner
