To resolve this problem, the processor in a keyboard “debounces” the keystrokes, by aggregating them across time to produce one “confirmed” keystroke. The first electronic keyboards had a typewriter key travel distance of 0.187 inches (4.75 mm), keytops were a half-inch (12.7 mm) high, and keyboards were about two inches thick. Over time, less key travel was accepted in the market, finally landing on 0.110 inches (2.79 mm). Coincident with this, Key Tronic was the first company to introduce a keyboard that was only about one inch thick. In 1978, Key Tronic Corporation introduced keyboards with capacitive-based switches, one of the first keyboard technologies not to use self-contained switches.

In other words, to convert the text from an image to editable text , a person could re-type it, or a computer could look at the image and deduce what each character is.

Win+D is one example of using this key to quickly show/hide the desktop. Another example of a modifier key combination is Ctrl+Alt+Del which can be used to shut down, sign out, access Task Manager, restart a computer, and more. The function of these keys isn’t as obvious because the instructions for using it aren’t laid out on the keyboard like the 7 key is.
