=head1 MISCELLANEOUS
Dunst can be paused by sending a notification with a summary of "DUNST_COMMAND_PAUSE"
and resumed with a summary of "DUNST_COMMAND_RESUME".
and resumed with a summary of "DUNST_COMMAND_RESUME". Alternatively you can send SIGUSR1 and SIGUSR2 to pause and unpause respectivly. For Example:
=item killall -SIGUSR1 dunst # pause
=item killall -SIGUSR2 dunst # resume
=back
When paused dunst will not display any notifications but keep all notifications in a queue.
This can for example be wrapped around a screen locker (i3lock, slock) to prevent flickering
of notifications through the lock and to read all missed notifications after returning to the computer.
