Computer keyboards as we know them today are a descendant of the typewriter, which was invented in the 1860s and had only a single Shift key used to switch between upper and lower case letters. Dec. The Ctrl and Alt keys were not even part of the original typewriter layout. So why were they added and why are there two of them now?
Keyboards have become an integral part of our daily life and serve as a gateway to the digital world. Although we usually underestimate their layout and functionality, there are logical reasons behind some design preferences. The presence of Ctrl, Shift and Alt keys on the keyboard is also one of these design preference products.

Have you ever wondered why there are two Ctrl, Shift and Alt keys on each side of your keyboard? These keys are called modifier keys because, as you know, when they are used together, they change the function of other keys. For example, Ctrl+C copies the selected text. If Shift+A is a capital A, Alt+F4 also closes the current window. So why do we need two of each modifier key? Isn’t just one of them enough? Is there a deeper reason behind this?
