canNavigateBack
Whether gestures and shortcuts for navigating backward are enabled.
The supported gestures are:
One-finger swipe on touchscreens
Horizontal scrolling on touchpads (usually two-finger swipe)
Back/forward mouse buttons
The keyboard back/forward keys are also supported, as well as the Alt+← shortcut for horizontal orientation, or Alt+↑ for vertical orientation.
If the orientation is horizontal, for right-to-left locales, gestures and shortcuts are reversed.
