This article describes how to enable Local Text Echo for published applications in Citrix Virtual Apps. 

NOTE: Local Text Echo is a legacy feature from XenApp 6.5 that has been refactored to work with Citrix Virtual Apps and Citrix Workspace App versions 1811 and greater. Support is limited to basic HTML and Windows text input fields. Citrix testing included Microsoft Internet Explorer and Notepad applications only.

Instructions

Configuring StoreFront
Edit the default.ica file on the StoreFront Server in c:\inetpub\wwwroot\Citrix\Store\App_Data and add the line below to the "Application" section with the desired value:

ZLKeyboardMode=1

0 – Feature is OFF, regardless of the configuration on the server.
1 – Feature is ON, regardless of the latency thresholds configured on the server.
2 – Feature is set to AUTO, and will turn on or off based on the latency thresholds configured on the server.

Configuring Citrix Workspace App (Windows client)
Create the following key and values in the Windows registry on the client machine where the Citrix Workspace App is installed:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client\Engine\Configuration\Advanced\Modules\GfxRender

(REG_DWORD) UseDirect3D = 0
(REG_DWORD) PresentDevice = 0

Configuring the server (VDA)
Run configuration tool ss3admin64.exe in C:\Program Files\Citrix\HDX\Bin on all Citrix servers hosting the application. 
Starting CVAD 2003 ss3admin64.exe is renamed to ss3admin.exe in C:\Program Files\Citrix\HDX\bin

Select a new application from the application menu and browse to the local executable (.EXE) file. By default, Enable local text echo for this application is selected.

 

Right click on the server name to access the server properties menu where latency thresholds can be adjusted. Once latency reaches the high threshold value Local Text Echo will be enabled and stay on until network latency drops below the low threshold value.
