AppleScript to open/click macOS notification banners via keyboard shortcut (Sequoia 15.x) — use with BetterTouchTool, Keyboard Maestro, etc.

open-notification-banner.applescript

-- Open/click the most recent macOS notification banner without using the mouse.
-- Tested on macOS Sequoia 15.6 (Apple M4).
--
-- Usage:
--   1. BetterTouchTool → Keyboard Shortcuts → Add shortcut → Run Apple Script (async in background)
--   2. Paste this script and assign your preferred hotkey (e.g. Ctrl+Shift+N)
--   3. Press the hotkey while a notification banner is visible on screen
--
-- Requirements:
--   • Your automation app (BetterTouchTool, Script Editor, etc.) must be enabled in:
--     System Settings → Privacy & Security → Accessibility
--
-- How it works:
--   The notification banner in Sequoia is an AXGroup with subrole AXNotificationCenterBanner
--   inside: window 1 → group 1 → group 1 → scroll area 1 → first group
--   It exposes an AXPress action ("Show Details") which is equivalent to clicking the banner.

tell application "System Events"
    tell process "NotificationCenter"
        try
            perform action "AXPress" of first group of scroll area 1 of group 1 of group 1 of window 1
        end try
    end tell
end tell
