RFE Add a keyboard shortcut to the notification area "clear" button
Some applications like Thunderbird and Slack do not clear their notifications from the notification area in Gnome when they are read. When you hit Super+v you can see a list of these notifications, but there does not seem to be a keyboard shortcut for the "clear" button in this area. You need to use arrow keys to navigate to the button then hit enter/space to clear all notifications in the notification area. It would be handy to be able to assign a shortcut key to that button.
