Over time, the function of the F5 key has evolved. It is now commonly used as a shortcut key in various applications to perform various tasks, such as reloading a web page, running a macro, or restarting an application.

Today, the F5 key is a widely used keyboard shortcut found on most modern computer keyboards. In some cases, the F5 key may also be used to access a computer's BIOS setup utility or boot menu. Despite its evolution, the original purpose of the F5 key as a refresh button remains unchanged, and it remains an essential tool for users who need to update the information displayed on their screens quickly.

The F5 key has a variety of functions across different devices and applications. Some of the most common functions include:

• Refreshing a web page: In web browsers, pressing the F5 key refreshes the current web page, updating it to display any new content or changes that have occurred since the last time it was loaded.
• Restarting an application: The F5 key is often used as a shortcut to restart an application. This is particularly useful for troubleshooting and fixing any issues affecting the application's performance.
• Running a macro: In certain applications, the F5 key may be used as a shortcut to run a macro. A macro is a series of pre-programmed actions that can be triggered with a single key press, making it an efficient way to perform repetitive tasks.

Note: The F5 key is only sometimes used for the same purpose across all devices and applications. As a result, it's always a good idea to check the documentation or help files for the device or application you're using to determine the specific function of the F5 key.

How to use the F5 key

The F5 key is a commonly used keyboard shortcut that can perform various tasks, depending on the device or application being used. Press the F5 key when the application or device that requires it is open to use the key.

If the F5 key additionally contains an icon or symbol, this denotes a supplementary use for the key. Press and hold the Fn key, which is often found at the bottom row of the keyboard, then press and hold the F5 key to activate the secondary function.

Note: The key may be the secondary function by default on some keyboards. For instance, you would need to hold down the Fn key while hitting the F5 key on an Apple computer in order to reach the F5 key's main function.

The keyboard will behave as if the Fn key is being pushed if the function lock (FnLk) is enabled until the lock is turned off. This means that pressing the F5 key will activate the secondary function, even if you do not hold down the Fn key.

To determine the specific function of the F5 key, it is always a good idea to consult the documentation or help files for the device or application you are using.
