The F7 is one I did not know and now I do.
Already starting to use it.

I like the hard work put in for the q.bat and h.bat but this is standard for anyone who has used a /bin/bash shell in a *nix environment. bash keeps history as far back as you want.

For someone who has to slide back and forth between cmd.exe and bash this is a big help. Although DOS/cmd.exe still has long way to go to match the basic power of a /bin/sh *nix shell.
