Top 20 Amazing Keyboard Shortcuts You Must Know | Complete Keyboard Tutorial | A to Z Shortcut Keys
A computer keyboard is an essential input device that enables users to input text, numbers, and commands into computers or other devices. It typically consists of a set of keys arranged in a specific configuration, including letters, numbers, punctuation marks, and special function keys. Keyboards can be wired or wireless, with various designs such as standard QWERTY layouts, ergonomic designs, and specialized gaming keyboards. When a key is pressed, it sends an electrical signal to the computer, which processes the input accordingly.
Computer users benefit from shortcut keys for several reasons:

Multitasking: Shortcut keys allow users to switch between applications or tasks seamlessly without interrupting workflow, particularly helpful when multitasking or working with multiple programs.
