'''^Z''' (Ctrl+z) is a shell keybind which suspends the foremost process. Windows' cmd.exe does not allow ^Z, but many UNIX shells will. When [[NetHack]] is suspended, the shell it was run from is brought into focus. NetHack is still alive, but it is frozen. Running the fg program will awaken NetHack.
