Mouse actions refer to the various movements and clicks performed using a computer mouse. The primary actions include clicking, double-clicking, and right-clicking. Clicking typically selects an item or opens a program, while double-clicking often opens files or applications. Right-clicking usually brings up a context menu with additional options related to the selected item. Another important mouse action is scrolling, which allows users to navigate through long documents or web pages. This is done by using the scroll wheel or dragging the scroll bar. Additionally, dragging involves holding down a mouse button while moving the cursor to select or move items on the screen.
