Why ⌃ ⌥ ⌘?BlurBox uses Control + Option + Command for its global shortcuts so they don’t collide with anything else. Most apps reserve plain ⌘ B or ⌘ V; the triple-modifier combo keeps BlurBox out of the way.
Shortcut not working?Another app may have registered the same combo first. Quit other utilities (Raycast, Alfred, Rectangle) one at a time to identify the conflict, or check the FAQ entry on this.
