What about using the "C-x 4" prefix?  We could define a new prefix map
bound to "C-x 4 h", then have all the bindings in *Help* be in the map
prefixed by "C-x 4 h".  For example, "C-x 4 h I" will run a command
which will produce the same effect as help-goto-lispref-info, using
the current *Help* window as its starting point.

We could support "C-x 5 h" prefixed key sequences in a similar manner,
for people who have Info buffers or *Help* buffers in another frame.

WDYT?
