Context menu, also known as the right-click menu, is a list of options that appears when you right-click on an object in a graphical user interface, such as a file, folder, or desktop. The context menu displays different options based on the type of object you are clicking on and its location, and it provides a quick way to access commonly used actions without navigating through menus or keyboard shortcuts. The options available in the context menu may include copy, paste, delete, rename, open, properties, and more, depending on the operating system and the application in use. The context menu can be customized to add or remove options according to your preferences, and it is an essential part of the user interface in modern operating systems.
