The keyboard, as a key member among computer input devices, is an important bridge for human-computer interaction.
 
Its layout is diverse. Common ones include the standard full-size keyboard, the compact 87-key keyboard, and the more portable 61-key keyboard, etc. The materials and craftsmanship of the keycaps also vary. Some are smooth and delicate, while others have a matte texture, providing users with a rich tactile experience.
 
The trigger mechanism of the keyboard keys affects the feel and response speed of input. Mechanical keyboards, with their unique shafts, such as the light linearity of the red shaft and the crisp paragraph feel of the blue shaft, are deeply loved by gamers and word workers. Membrane keyboards occupy a certain market share with their mute feature and lower price.
 
Meanwhile, the keyboard also has rich functions. Multimedia shortcut keys can conveniently control operations such as volume and play/pause. Some high-end keyboards also support custom macro programming to meet users' demands for personalized operations.
 
In terms of appearance design, keyboards are paying more and more attention to aesthetics. From the simple black and white color matching to the cool RGB lighting effects, it meets the pursuit of style and personality of different users.
 
In conclusion, the keyboard is not only an input tool but also a sharp weapon to show personality and improve operational efficiency.
