the computer keyboard
Computer keyboards present alphanumeric keys (letters and numbers), punctuation (period, comma, etc.) and special keys (which fulfill different functions, for example).
Among these special keys are, for example, those known as function keys, which are those that are located at the top of the keyboard and that allow us to directly access a series of programs or tools simply by themselves or by using them in combination with others.
And all this without forgetting the editing keys, which are what allow the computer user to carry out operations such as deleting text, moving through pages and documents quickly, or inserting various elements. In this case, these keys include Home, Delete, End or Page Down.
The arrow keys, the four that have arrows represented, are also equally important on any computer. As its name suggests, they are the ones that give us the opportunity to move to the left, to the right, down or up through the document that we have open as well as through the web page that we are consulting.
Combination and layout of the keys
In addition to all of the above, we have to emphasize that the keyboard gives us the opportunity to speed up tasks by combining the different keys that shape it. Thus, for example, the use of Ctrl + N allows us to make the selected word or phrase appear in bold while the joint use of the CTRL + G keys allows us to save the document that we have open and in which we are working. These are combinations that do not require us to use the drop-down menus of the different programs.
