### 20`` drracket:help-desk

> > procedure

> > (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.

Opens the user’s web browser and points it at the license for PLT software.
