Using the Call Mode overlay in the desktop app

In the desktop app, open a script in the prompter and click the float / call-overlay button in the bottom toolbar (or say "Hey Fox, open call mode"). A transparent, always-on-top window opens with the script and starts voice tracking. Hover its top edge for the bar: "ScriptFox · drag to move" on the left, "Click-through: on/off" and ✕ ("Close overlay") on the right.

• Click-through on: clicks pass through to Zoom, OBS, or whatever is underneath, so you can't drag or resize the overlay until you switch it off (the bar button, the tray icon → "Toggle click-through", or Ctrl+Shift+L).
• Hotkeys work from any app: Ctrl+Shift+O shows or hides the overlay, Ctrl+Shift+Space plays or pauses.
• Opacity, font size, and colors are set in the overlay's own Settings and saved separately from the main prompter.
• The overlay is hidden from screen sharing and recordings by default, so your audience never sees it. To include it on purpose, tick the tray icon → "Show overlay in recordings".

The tray icon also has "Show overlay" / "Hide overlay" and "Close overlay". If the overlay seems missing after "Show overlay", it may be parked on another display.
