^Z
The ^Z (Ctrl+z) command suspends nethack in environments that support this. ^Z is the usual *NIX[1] shell keybind which suspends the foremost process, but nethack is suspended using ^Z no matter what the current setting is. Windows' cmd.exe does not allow ^Z, but many *NIX 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 shell builtin will awaken NetHack.
