Or did you mean: like `help-for-help'?  That's similar.  Scrolling
`help-for-help' with the mouse wheel loses the prompt for a key, btw,
only scrolling with the scroll bar works as expected for me.

Note that `help-for-help' is a front end for help commands, while
`calc-dispatch-help' more or less only summarizes the commands reachable
from the outside Calc C-x * prefix.  The Calc help stuff doesn't even
seem to be reachable from C-x *.

BTW, there is a way to get that buffer directly and without a key prompt:
C-h f calc-dispatch-help RET.
