You can use native operating system gestures from your touch-based mobile device when you are connected to a Windows 8, Windows 10, or Windows Server 2012 remote desktop, or to a remote application that is hosted on Windows Server 2012. For example, you can touch, hold, and release an item on a Windows 8 desktop to display the item's context menu.
When touch redirection is enabled, you can use only native operating system touch gestures. Horizon Client local gestures, such as double-click and pinch, no longer work. You must drag the Unity Touch tab button to display the Unity Touch sidebar.
Touch redirection is enabled by default when you connect to a Windows 8, Windows 10, or Windows Server 2012 remote desktop, or to a remote application that is hosted on Windows Server 2012.
To disable touch redirection, open Settings, tap Touch, and deselect the Windows native touch gestures check box. If you are connected to a remote desktop or application in full-screen mode, tap the Horizon Client Tools radial menu icon and tap the gear icon. If you are not using full-screen mode, Settings is in the menu in the upper-right corner of the Horizon Client toolbar. If you are not connected to a remote desktop or application, tap the gear icon in the upper right corner of the Horizon Client window.
