With Horizon Client 3.2 and later, you can use native operating system gestures from your touch-based mobile device when you are connected to a Windows 8 or Windows Server 2012 remote desktop or a remote application 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 or Windows Server 2012 remote desktop or remote application hosted on Windows Server 2012.
If you are using the remote desktop in full-screen mode, you can disable touch redirection by tapping the Horizon Client Tools radial menu icon, tapping the Settings (gear) icon, tapping General settings, and deselecting the Windows native touch gesture check box. If you are not using full-screen mode, Settings is in the menu in the upper-right corner of the Horizon Client toolbar.
