+#   When specifying a different terminal, additional arguments are supported. In particular, you can
+#   append a specific title to the terminal and set it to "nofocus" in your WM config.
+#   E.g for alacritty and i3, you can set $NNN_TERMINAL to 'alacritty --title preview-tui' and add
+#   'no_focus [title="preview-tui"]' to your i3 config file.
