I have used flicks on every Windows tablet that I have used. I did go into a lot of detail about Flicks with the Lenovo IdeaPad S10-3T. Flicks allow you to quickly access many commonly used functions. To activate flicks you would slide quickly the pen to a direction.
You can add more Flicks by activating the "Navigation and Editing Flicks" which add diagonal gestures. Windows let's you customize these Flicks, and doing this can improve your tablet experience.
Flicks can be activated by using your digitizer or finger. The activation can be "precise" or "relaxed", adjust to suit your needs through the settings.
