Operate Mode

Operate Mode is an operator-only feature that lets you see exactly what each connected viewer screen is displaying — in real-time — while controlling all display settings from a single panel.

Activating Operate Mode

Start a session and connect at least one viewer screen (local or remote).
When a display connects, a Read / Operate toggle appears in the top navigation bar. Click Operate.
The operator's reading view is replaced by a live mirror of the selected viewer's display.

Note: The operator's prompter continues scrolling normally behind the Operate Mode overlay. Playback is not interrupted when entering or exiting this mode.

Interface Layout

The Operate Mode interface is divided into three main areas:

1. Viewer Tabs (Top)

One tab per connected viewer. Click a tab to switch which viewer you're monitoring.

You can click the Pencil icon on any tab to rename that viewer.
Disconnected viewers dim out and show a timestamp of when they disconnected. They are retained for 60 seconds so you can see what happened.

2. Mirror Preview (Center)

A scaled, real-time replica of the selected viewer's screen.

Shows exactly what the viewer sees: font size, margins, cue markers, and scroll position.
You can drag the cue marker position directly on the mirror.

3. Settings Panel (Right)

Contains collapsible sections to control the selected viewer:

Text Settings: Font size, line height, and margin sliders.
Display Settings: Cue marker style, mirror mode (flip horizontally/vertically for beam splitters), fullscreen toggle, and clean display (hides viewer control bar).
Remote Screen Layout: A miniature map showing where the prompter window sits on the viewer's physical screen. This is helpful to verify if a desktop viewer window is maximized or properly positioned.

Fullscreen Control

The fullscreen toggle uses a request/confirm pattern:

Clicking the switch sends a fullscreen request to the viewer. The switch enters a pending state (amber pulse).
If the browser can enter fullscreen automatically (typical for desktop), it does so immediately.
If not (typical for mobile/tablet), the viewer shows a "Tap to enter fullscreen" overlay that auto-dismisses after 10 seconds.
The switch always reflects the viewer's actual fullscreen state. If the viewer declines or exits fullscreen (e.g., using the Escape key or swipe gesture), the switch turns off.
Clicking the switch again while it's pending will cancel the request.

Connection Health

A colored dot next to the connection type indicates the viewer's network health:

🟢 Green: Reports received within the last 12 seconds (Excellent).
🟡 Amber: No report for 12–20 seconds (Degraded).
🔴 Red: No report for 20+ seconds (Poor connection or stale viewer).

Tips & Edge Cases

Mouse Wheel: Scrolling with the mouse wheel while your cursor is over the center monitor area will still scroll the operator's prompter. Scrolling over the right settings panel scrolls the settings, not the prompter.
Persistence: Your Operate Mode state (on/off) and per-viewer settings (font, margin, flip, etc.) are saved locally and persist across page reloads.
Viewer Coast Mode: If a viewer loses its network connection while the teleprompter is scrolling, it enters "coast mode" — continuing to scroll at the last known speed. A pulsing amber dot appears on their screen. When the connection is restored, the viewer automatically re-syncs with the operator.
Mobile Constraints: Some mobile browsers restrict fullscreen access or wake locks. If the controls appear unresponsive, the device may need to be plugged in or use a different browser.
