Volume & Brightness HUD
DynaKeys — replace the default macOS system overlay with an elegant island display.
Volume & Brightness HUD (DynaKeys)
DynaKeys intercepts the system events fired when you press volume, brightness, or keyboard backlight keys, and displays the change in the island instead of the default macOS full-screen overlay.
What it replaces
| Key | System default | SuperIsland |
|---|---|---|
| Volume Up/Down | Full-screen speaker icon | Island compact + expanded |
| Mute | Full-screen muted icon | Island with muted indicator |
| Brightness Up/Down | Full-screen sun icon | Island compact + expanded |
| Keyboard Backlight | Full-screen keyboard icon | Island compact |
Compact state
During an active HUD event, the compact island shows the event icon and a small progress pill.
🔊 ████████░░ 70%Expanded state
The island expands to show:
- Icon (speaker / sun / keyboard)
- Percentage with large typography
- Animated fill bar
- Output device name (for volume — e.g., "AirPods Pro")
Auto-dismiss
The expanded HUD dismisses automatically 1.5 seconds after the last key press.
Implementation note
DynaKeys uses a private CGEventTap to intercept media key events before they reach the default HUD. It does not consume the events — the volume/brightness still changes; only the visual is replaced.
