Can you explain the history of the f5 keys?
The F5 key on a computer keyboard is typically used to refresh or reload a page in a web browser. However, the origins of the F5 key and its use in computers go back several decades.

The function keys, including F1 through F12, were first introduced on the IBM 3270 terminal in the 1970s. These keys were designed to provide quick access to commonly used computer commands, such as saving a file, opening a new window, or printing a document. Over time, the specific functions associated with each of the function keys have evolved, with different software applications and operating systems using them in different ways.

In the early days of the World Wide Web, web browsers such as Mosaic and Netscape Navigator used the F5 key as a way to refresh or reload a page. This was especially useful as web pages in the early days of the Internet were often slow to load and prone to errors, and the F5 key allowed users to quickly reload a page if it didn't display correctly.

Today, the F5 key continues to be widely used as a refresh or reload button in web browsers, although some browsers have added other functions to it as well. Additionally, the F5 key is used in other software applications, such as image and video editors, as a shortcut for frequently used functions.
