procedure
(drracket:help-desk:help-desk [ search-key search-context parent #:language-family language-family]) → any search-key : (or/c #f string?) = #f
search-context : (or/c #f string? (list/c string? string?)) = #f parent : (or/c (is-a?/c frame%) (is-a?/c dialog%) #f) = #f language-family : string? = #f
if search-key is a string, performs a search in the docs with
search-key and search-context.
Otherwise, calls send-language-family-page. The language-family
argument is passed along in either case.
The search may involve asking the user a question, in which case the
dialog with the question uses parent as its parent.
