Computer mice serve several key functions:
- Pointer Control: They move a cursor on the screen, allowing users to navigate and interact with the graphical interface.
- Selection: Users can click to select items, such as files or text, and interact with interface elements like buttons and menus.
- Scrolling: Many mice have scroll wheels or touch surfaces that allow users to scroll through long documents or web pages.
- Dragging and Dropping: Users can click and hold to move items or highlight text, then drop them in a different location.
- Contextual Menus: Right-clicking often brings up context-sensitive menus with additional options relevant to the current task or selection.
- Additional Buttons: Many mice have extra buttons for programmable functions, such as back and forward navigation in browsers or specific commands in software applications.
