Our computers, or the vast majority of them, have on their top row a series of keys that almost nobody uses. And yet, they can save us a lot of time, or at least they did in the early days of computing. These are the 12 keys from F1 to F12.

Today, many of the functions they perform coexist with modern user interfaces, easier or more intuitive, which gradually condemn them to a more decorative or sentimental function. We use the mouse more than keyboard shortcuts. But they can still save you a lot of time if you get used to using them.

This is the case of the F5 key, the most famous and most used of all, which we can use to refresh our computer, that is, when we are impatient because some Internet page does not load, or does not load at the speed we want. We also tell you what the other 11 keys above are for.
