plugins/bgnotify/README.md

@@ -38,6 +38,7 @@ One can configure a few things:
 - `bgnotify_bell` enabled or disables the terminal bell (default true)
 - `bgnotify_threshold` sets the notification threshold time (default 6 seconds)
 - `function bgnotify_formatted` lets you change the notification. You can for instance customize the message and pass in an icon.
+- `bgnotify_extraargs` appends extra args to notifier (e.g. `-e` for notify-send to create a transient notification)
 
 Use these by adding a function definition before the your call to source. Example:
