Were you thinking of a command that specifically targets the symbol from
a displayed *Help* buffer, so the user would do e.g.

C-h v VAR RET   ; shows *Help* for VAR
C-h SOMETHING   ; finds source for VAR

where C-h SOMETHING's implementation would do (a smarter version of)
(with-current-buffer "*Help*"
  (help-view-source))

?  Can't say I remember such a command; otherwise, I'm reminded of
find-func's find-function-setup-keys, which installs a bunch of
upper-case bindings on the C-x map (resp. C-x [45] maps) to invoke the
find-* commands (resp. find-*-other-{window,frame}).
