With the touch redirection feature, you can use native operating system gestures from a touch-based mobile device in a remote desktop or published application. For example, you can touch, hold, and release an item on a Windows 8 remote desktop to display the item's context menu.
When touch redirection is enabled, 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 published application that is hosted on a Windows Server 2012 server.
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 published 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, tap Settings in the menu in the upper-right corner of the Horizon Client toolbar. If you are not connected to a remote desktop or published application, tap the gear icon in the upper right corner of the Horizon Client window.
