Buttons refer to all buttons on a mouse other than the left and right arrow keys, including the scroll wheel, side buttons, and DPI button. Buttons affect the mouse's functionality and ease of use; generally, more buttons mean greater flexibility and a more practical mouse.
Different people have different button needs. Generally, you can choose buttons based on your usage scenario and habits. Office users are generally suited to mice with fewer buttons to avoid accidental clicks or interference; gamers generally prefer mice with more buttons to increase shortcut operations or customization options. Button quality and feel are also important. Generally, Omron microswitches are a good choice, offering good feedback and longevity.
