It's somewhat ill-defined as functions can be created at any moment.

But as a start

lapply(search(), ls)

might get you going.

Though my original idea was to access the indices of the HTML help
system, with something like help.start() -> packages -> whichever
package you want. I'm sure this can all be accessed automatically as
well.

Also, let's please keep emails on the list and avoid top-posting in so
far as possible.
