(drracket:help-desk:help-desk [ search-key search-context parent]) → 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
if search-key is a string, performs a search in the docs with
search-key and search-context.
Otherwise, calls send-main-page with no arguments.
The search may involve asking the user a question, in which case the
dialog with the question uses parent as its parent.
