How about improving `C-h k RET' here, to let
users know that?  Neither the command name
nor the doc string really suggests that.  IOW,
can we please elaborate about "near point"?

What's more, though some of the doc string says
"near point", other parts say "on".

 "If point is on a reference..."
 "If point is in a menu item..."

And this mistakenly says that "point" is "on",
or "in" something, whereas point is a position,
not something that is at, on, or in something
else.  It's the other way around: something is
_at_ a position (such as point).
