How do you press f5 on mac?

On a Mac, you can press the F5 key directly if your keyboard has an F5 key. However, if the F5 key is set to perform a specific function (like adjusting brightness), you may need to hold down the "Fn" key while pressing F5 to use it as a standard function key. Alternatively, you can use the shortcut "Command + R" in most applications to refresh a page.
