Scribes plugin. Opens current file directory in file manager
Default shortcut <crtl>+<alt>+l opens editor file directory in file manager.
Because plugin uses xdg-open for opening directory you must have mimeopen util installed in your system, or else directory will be opened in Firefox.
AFAIK, debian based distributives have mimeopen from the box. For ArchLinux you need install perl-file-mimeinfo package.
