So the shift+PageDown and shift+PageUp is missing. But PageUp is a v= ary important=0D feature when system panic or reset. I can get log by PageUp before, but now= there is no=0D way to get. Especially on the server system, we always use bmc to control c= omputer.=0D So I hope the community can add this feature back.=
