fnottctl is used to interact (dismiss notifications, show and select action for notifications) with
fnott(1).
The most common operation is fnottctldismiss. This will dismiss the highest priority notification. You
might want to bind this to a keyboard shortcut in your Wayland compositor configuration. This is the same
as right clicking the notification.
To see, and select between, actions associated with the notification, use fnottctlactions. This requires
a dmenu-like utility to have been configured in fnott.ini(5).
Finally, you can trigger the notification's default action (an action named default) and dismiss it
simultaneously with dismiss-with-default-action. This is the same as left clicking the notification.
You can optionally specify a notification ID, to dismiss (or show actions for) a specific notification
instead of the highest priority one.
For dismiss, there is also the special ID all which will, not unsurprisingly, dismiss all notifications.
