It was probably a context menu or shortcut menu that appears when you right-click something on a computer. The exact options depend on what you clicked, but common actions include open, copy, paste, rename, properties, and other item-specific commands.

What it does

Right-clicking is the secondary mouse click, and it usually opens a menu of actions related to the file, icon, text, or screen area under your pointer. On laptops or touchpads, the same thing can happen with a two-finger tap, a lower-right corner tap, or a dedicated secondary-click gesture depending on the device.

Why it changes

The menu is context-sensitive , which means it changes based on where you click. For example, right-clicking a desktop can show display options, while right-clicking a file can show actions like open or properties.

If it wasn’t a menu

If you right-clicked in a browser, app, or game, it may have triggered a custom action instead of a standard menu, since programs can assign their own right-click behavior.
