This requires a two level search, but is probably more useful than just
a list of function names:
Run help.start() to get into the main help page.
Click on "Packages". Now you'll see a list of all installed packages
and their titles.
Choose an interesting package, and click on its name. Now you'll see a
list of most help aliases (generally all functions, plus some other
things) and the title of the associated help page.
You don't see all help aliases: S4 method documentation tends to have a
lot of aliases, and some of those are suppressed. But you should see
all help pages at least once.
