**Which key on a Windows keyboard sets fullscreen mode in browsers?**
Verified**Explanation:**
The F11 key is a universal keyboard shortcut that toggles fullscreen mode in most web browsers on Windows systems. When you press F11 while browsing the internet, your browser window expands to fill the entire screen, hiding the address bar, bookmarks toolbar, and other browser interface elements. This gives you maximum viewing space for websites and web content.
This keyboard shortcut works consistently across all major browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, and Internet Explorer. The F11 key serves as a toggle switch – pressing it once enters fullscreen mode, and pressing it again returns the browser to its normal windowed view.
Fullscreen mode is particularly useful when you want to focus on reading articles, watching videos, viewing presentations, or working with web applications without distractions. It's also helpful for presentations where you want to display web content to an audience without showing browser toolbars or other desktop elements.
The F11 function extends beyond just web browsers – it also works in many other applications like media players, document viewers, and presentation software. However, its most common and recognized use is for browser fullscreen mode, making it an essential keyboard shortcut for efficient web browsing and computer usage.
