Computer keyboards usually have a qwerty layout, which is one of the most common keyboard layouts and gets its name from the first six letters of the top line of the letter keys on the keyboard. In addition to alphabetic keys, keyboards also include numeric keys, symbol keys, function keys, and control keys. Understanding the keyboard layout helps users locate keys quickly and accurately.
Alphanumeric and numeric keys are the most basic keys on a keyboard and are used to enter words and numbers. The letter key is located on the keyboard** and is used to enter 26 English letters; Numeric keys are located on the right side of the keyboard and include 10 numeric keys and symbol keys such as addition, subtraction, multiplication and division, which are used to enter numbers and perform simple arithmetic.
Function keys are located at the top or side of the keyboard and are used to perform specific functional actions. Common function keys include F1 to F12, which are often associated with different software programs or operating system functions, such as the F1 key is usually used to open a help document, while the F5 key is usually used to refresh a web page.
The control keys are used to control the editing of the text and the movement of the cursor. Common controls include enter, backspace, tab, shift, ctrl, and alt. These keys can be used alone or in combination with other keys for more functionality.
Cursor keys are used to move the cursor in text editors, browsers, and other applications. Common cursor keys include the arrow keys (up, down, left, right), the home button (to move to the beginning of the line), the end key (to move to the end of the line), and the page up and page down keys (to turn up or down).
In addition to the common keys mentioned above, there are some special function keys, such as the print screen key (for capturing screenshots), the insert key (for switching between insert mode and replace mode), the esc key (for canceling the current operation), the windows key (for opening the start menu), etc. These special function keys can increase the user's productivity in specific situations.
A shortcut is a quick way to perform a specific function by pressing a key combination on the keyboard. For example, Ctrl+C is used to copy the selected content, Ctrl+V is used to paste the copied content, Ctrl+Z is used to undo the previous operation, etc. Proficiency in shortcut keys can greatly improve work efficiency.
In addition to understanding the physical keys of the keyboard, it is also necessary to understand the drivers and settings of the keyboard.

When needed, users can configure the keyboard through the settings interface provided by the operating system, such as adjusting the keyboard sensitivity, changing the key mapping, etc.
