I’d heard before that Windows 7 had some built-in mouse gestures, but aside from the Aero Shake  and Snap features, I haven’t been able to unearth much else.
So the next time you want to access the jump list for a program in the taskbar, do this:
Click on the program’s taskbar icon once, hold that click and slowly drag up.
…and there’s your jumplist!
I’ll keep diggin’ around to see if I can find more Windows 7 mouse gestures.
