To open a Jump List of Windows 7 in sliding mode

In general, for Windows 7 users who need to open a program's jumplists (Jump List), you can open it by right-clicking the program's taskbar shortcut icon. But for touchpad, trackball (like ThinkPad's Little Red Hat) and multi-touch users, the right button is not very convenient in a sense (of course, now the Touchpad function is already very powerful), is there a simpler way?

In fact, Microsoft has considered this situation, but also provides a corresponding solution. In fact, it is also very simple, there must be users inadvertently found that is left-click after the mouse moved up, can achieve the same effect.
