When we showed you how to master Windows 7’s new Jump Lists feature, there was one extremely useful tip that we left out: you can also access them from your keyboard.
The Into Windows blog points out a built-in shortcut key in Windows 7 that opens up the Jump Lists for the first 9 taskbar icons—just like you can use Win+1, Win+2, etc to cycle between open windows on the taskbar or launch an application, you can use the Win+Alt+1 shortcut key combination to open up the Jump List for the icon in that position in the taskbar.
In the example screenshot, using Win+Alt+4 opened the Jump List menu for Microsoft Outlook, since it’s sitting at the fourth position on the taskbar—or you could have used Win+Alt+1 to open up the Jump List for Windows Explorer. It’s an excellent way to more quickly access one of the best underhyped features in Windows 7 and access recently used items more easily.
