There is no built-in function that opens that page.  If you want to
write one, the URL is

http://127.0.0.1:XXXXXX/library/PPPPPP/html/00Index.html

where

  -- XXXXXX is the port being used for the help system, available via
tools:::httpdPort.  (If that is 0, call tools::startDynamicHelp() to
start it up.)

  -- PPPPPP is the name of the package whose index you want.

You can look through the tools:::httpd function for other patterns.
