Definition - What does Contextual Menu mean?
A contextual menu is a graphical user interface menu that appears on user interactions such as right-mouse clicks or middle-click mouse operation.

Techopedia explains Contextual Menu
Contextual menus provide access to actions that pertain to specific items in the user interface. They act much like left-mouse-button clicks, and operations are offered according to the user's choices.
Contextual menus are opened when users interact with their interface, and they target a region of the graphical user interface that supports context menus. On computers running on Windows or Unix, context menus are opened by clicking a secondary mouse button. In systems that support a one-button mouse, context menus are opened by pressing and holding that primary button. In certain scenarios, context menus are hierarchically organized, allowing navigation through different levels of the structure.
