To go full screen, the fastest method on most computers and browsers is to press the F11 key while the window you want is active.

Quick Scoop: Easiest Full‑Screen Tricks

  • On Windows in Chrome, Edge, Firefox, File Explorer, and many apps, press F11 to toggle full screen on and off.
  • On some laptops, you may need Fn + F11 instead of just F11.
  • Many games and console windows (like Command Prompt) use Alt + Enter to switch between windowed and full screen.
  • You can always use the maximize button (the square icon in the top‑right of a window) to make it fill most of the screen, even if it’s not “true” full screen.

Example: If you’re watching a video in your browser, click on the video and press F11 – the browser chrome disappears and the video fills the whole display.

TL;DR: Click the window you want, press F11 , and if that doesn’t work, try Fn + F11 or Alt + Enter , or use the window’s maximize button.
