You may know that pressing the Windows key along with a number will open a program you have pinned on the taskbar, as if you clicked the program’s icon with the mouse.

To show the context menu (jump list) associated with a program’s icon on the taskbar, you can right click on the icon, but you can also use again a keyboard shortcut, which in this case is Win+Alt+Number.

Therefore, if you have MS Word as the first icon pinned on the taskbar, pressing Win+1 will open Word, and pressing Win+Alt+1 will open Word’s jump list / context menu, at the taskbar.
