dunst
The community/apps/dunst directory contains files that integrate the Dunst notification daemon with Talon.
The file dunst.talon defines Talon commands for controlling Dunst.
Specifically, it defines the following commands:
show notifications: bound toctrl-`, this command likely focuses or brings the Dunst notification window to the foreground.dismiss [notifications]: executesdunstctl close, which dismisses the currently displayed notification.dismiss all [notifications]: executesdunstctl close-all, which dismisses all currently displayed notifications.
The commented-out lines are likely experimental or alternative commands that the author has chosen to disable. They would have provided the ability to pause, resume, and test notifications.
