What Is Shortcut Display?

Shortcut display is a specific use case of keystroke overlay, focused on surfacing keyboard shortcuts — multi-key combinations that trigger application commands — rather than all key presses. The distinction matters in practice: a recording of someone writing code produces hundreds of individual character key presses that are not interesting to display as overlays. The genuinely educational key events are the modifier-based shortcuts: ⌘Z to undo, ⌘⇧P to open a command palette, or a custom app shortcut that the presenter wants to highlight. A well-designed shortcut display filters for modifier-key chords and suppresses bare character presses, keeping the overlay relevant.

Shortcut display is particularly valuable in productivity tool tutorials, IDE walkthroughs, and creative application demos where keyboard proficiency is a core skill the audience is trying to develop. A viewer who can read the shortcuts being used in real time can immediately try them in the app — the tutorial becomes interactive rather than passive. This is the pedagogical advantage of shortcut display over narration alone: hearing "I'll press Command-Shift-F to format" while also seeing "⌘⇧F" appear on screen creates dual encoding that improves retention.

In Limelight, shortcut display is part of the keystroke display feature activated with ⌃⌥2. The display prioritizes modifier-key chords and uses macOS's native symbol notation so the displayed shortcut matches exactly what viewers will see when they look up the same command in the application's menu bar or help documentation. This consistency between the in-video overlay and the in-app notation removes a common source of confusion where a video shows "Ctrl+Shift+P" while macOS menus show "⌘⇧P" — different representations of different keyboard shortcuts that students have to mentally reconcile.
