Proposed behaviors

Main view

*   **one finger** — cursor
*   **two** fingers — content manipulation
    *   Sites can override all two finger gestures passed to the
                content area
    *   Pinch - defaults to page zoom
    *   Rotate - defaults to nothing
    *   Translate - defaults to scroll
*   **three** fingers horizontal
    *   tab switch
*   **three** fingers up — into overview
*   **three** fingers down — focus panels
*   **four** fingers up — into overview
*   **four** fingers down — focus panels
*   **four** fingers horizontal — window switching
*   **three** finger group translate — back/forward or tab switch
            (reverse of horizontal's behavior)
*   **three** finger group rotate — problematic because of two
            finger with anchored thumb
*   **one** finger left/right edge in — back/forward
*   **one** finger left/right edge out — forward/back, or sidebar
            reveal
*   **one** finger top edge in — overview
*   **one** finger bottom edge in — panels

Overview

*   **two** fingers horizontal — switch tabs
*   **two** fingers up/down? — close tab
*   **three** fingers — switch windows
*   **four** fingers — window switching
*   **three** fingers down — out of overview
*   **four** fingers down — out of overview
*   **three** or **four** fingers up — logout

Panels

*   **two** fingers = scroll current panel
