  {
    command: "application:toggle-mode",
    selector: "body",
    linuxKeys: ["Ctrl Shift M"], // only linux
    macKeys: ["Cmd Shift Z"], // only mac
    winKeys: ["Ctrl Shift B"], // only windows
    keys: ["Accel Shift U"] // default shortcut
  }
  

• Added options for jupyter lab clean to clean specific parts of the build, such as --extensions, --settings, --static, and --all (#7583, #6734)
