function my_editor_content() {
    global $post;
    return search_keywords($post->post_content, $keyword1,$keyword2,$keyword3);
}

Answer 1

I think you need to hook into default_content like this

add_filter( 'default_content', 'my_editor_content' );

function my_editor_content( $content ) {

$content = "This is my default content!";

return $content;
}
