Mouse operations refer to the actions performed using a computer mouse, a pointing device that allows users to interact with a computer's graphical user interface. Common operations include clicking, which selects items; double-clicking, which opens files or applications; and right-clicking, which brings up context menus with additional options. Another important operation is scrolling, which allows users to navigate through long documents or web pages by moving the mouse wheel. Additionally, dragging and dropping enables users to move files or objects by clicking and holding the mouse button while moving the cursor. These operations enhance user experience with computers and software applications.
