The Context Menu is a pop-up menu that appears whenever you click inside JEditor's editing area with the right mouse button, use the Menu/Application key on your keyboard or the Shift+F10 keyboard shortcut.
The menu is context-sensitive which means that the options displayed in it depend on the element that you click. If, for example, you press the right mouse button while inside a table, you will see some table-specific options available in its context menu.
Note that for some more complex objects, like a table, the context menu might include sub-menus with further options. To open the sub-menu, go to the menu option containing a small right-pointing arrow and either click it with your mouse or use the Right Arrow key on your keyboard. To return to the parent menu, use your mouse or the Left Arrow key.
Important: to disable the context menu (for example to use the browser's dictionary) hold CTRL when doing a right-click.
