This minor mode adds similar functionality to the SLIME macroexpand mode. It’s activated using C-x RET and then support further macro expansion in the macro view. It also does macroexpand-all using C-x M-m.
Once in the macroexpand view g can be used to refresh the macro expansion and q will bury the buffer.
