**With this action, you can switch the application (web app, PWA, desktop app) to full screen on the user's device.**

This action is particularly useful if you are creating a web app/PWA, or a desktop app for Windows, macOS, or Linux that opens in a window. Indeed, for this type of format, the application does not automatically open in full screen. The 'Enter Full Screen / Exit Full Screen' action allows you to address this. A desktop app exported with **Full screen** on Windows or **Kiosk mode** on macOS and Linux already opens in full screen, and this action does not take it out (see Kiosk Mode on [Windows](https://docs.pandasuite.com/essentials/desktop-publishing/kiosk-mode-for-windows/), [macOS](https://docs.pandasuite.com/essentials/desktop-publishing/kiosk-mode-for-macos/), or [Linux](https://docs.pandasuite.com/essentials/desktop-publishing/kiosk-mode-for-linux/)).
