Citrix Virtual Apps and Desktops offers rich configurations around keyboards and input method editors to support user and IT admin requirements, including languages and platforms. But configuring keyboards and IMEs correctly can be difficult because of factors like the variety of Citrix Workspace app clients, OS platforms, and more.
Keyboard Synchronization Mode
Citrix Virtual Apps and Desktops supports both client keyboards and VDA-side keyboards. If the client keyboard layout is different with VDAs, one common issue is which side of the keyboard layout is applied. The basic rules are:
- If the client is Citrix Workspace app for Windows, or set as Citrix Workspace app for Linux in Mode 1, the VDA-side keyboard will be applied, which means key input is determined by the VDA-side keyboard layout.
- If the client is a non-Windows Citrix Workspace app (Mac, Linux, iOS, or Android), the client keyboard will be applied, which means key input is determined by client side keyboard layout.
- If rules 1 and 2 don’t work, there might be incorrect configurations or Citrix Virtual Apps and Desktops doesn’t support that type of scenario. If this is the case, contact Citrix Customer Service.
Another common issue is which keyboard layout is set on the VDA side when users log in or reconnect to a session. Does it sync the client keyboard layout to VDA side? If it doesn’t, which keyboard layout is used? It depends on the keyboard synchronization mode settings. Citrix Virtual Apps and Desktops supports four keyboard synchronization modes:
- Mode 1: Use the VDA side default keyboard when logging in or reconnecting to the VDA. This is the default setting when the client is Citrix Workspace app for Android and Citrix Workspace app for iOS. You can configure this setting through the client configure file or icafile in StoreFront. Any keyboard layout change in client side will not be synchronized to the VDA side in session.
- Mode 2: Use a specific keyboard when logging in or reconnecting to the VDA. A specific keyboard layout can be configured through the client configuration file or icafile in StoreFront when logging in or reconnecting to the VDA. Any keyboard layout change on the client side will not be synchronized to the VDA side in session.
- Mode 3: Only synchronize the VDA-side keyboard with client default keyboard when logging in or reconnecting to the VDA. This is the default setting when the client is Citrix Workspace app for Windows, Mac, or Linux. Any keyboard layout change on the client side will not be synchronized to the VDA side in session.
- Mode 4: Synchronize the VDA-side keyboard with the client keyboard dynamically in the VDA session. When the user changes the client keyboard, the VDA keyboard will be synchronized automatically in session. Both the client and VDA have settings to enable this mode.
All four synchronization modes are exclusive, and individual clients can only work in one of the modes. If a user has more than one client, I don’t recommend setting different synchronization modes for every client, even if you can. That causes confusion about which keyboard will be applied in session when logging in and reconnecting through a different client.
Using Mode 1 and Mode 2 may cause inconsistency between the client keyboard and the VDA-side keyboard. For example, the client-side keyboard might display the German keyboard icon, but the VDA side might display the English keyboard icon. Mode 1 and Mode 2 are normally used in deployments that use only one kind of keyboard layout and where the client side does not need to change the keyboard layout. For Windows OS, the VDA side default keyboard depends on the Windows OS language, the current user profile setting, and the Windows OS configurations. The keyboard layout in VDA is unknown in Mode 1, and using this mode is not recommended.

Table 1.2 Sync Mode Supportability in Different Platform of Citrix Workspace app
Mode 1: Configure “Use VDA side default keyboard when logging in or reconnecting to the VDA” Mode
This mode will not synchronize client keyboard layout to VDA-side when logging in or reconnecting to the VDA. There are two levels for configuring this mode. One is through modifying the local configure file installed with the Citrix Workspace app for each user. The other is through modifying default.ica in the StoreFront server. The StoreFront configuration has higher priority than the client local file configuration.

This mode will synchronize the client keyboard to the VDA side in the session every time the client keyboard is changed. It will always maintain keyboard consistency between the client and the VDA side. This mode does not support synchronizing of the VDA side keyboard to the client side if users change the keyboard in the VDA side. For CJK (Chinese, Japanese, Korean) users, this mode will enable them to use the client IME instead of the VDA-side IME. This mode is also called the Client Keyboard Synchronization and Generic Client IME feature, and you must configure both the client and VDA sides to enable this feature.

Non-Windows Citrix Workspace app support
Enable Unicode Keyboard Layout Mapping for Windows VDA
The difference in keyboard layout among operating systems can cause key mapping issues. For example, the Mac France keyboard layout is different from Windows. Citrix Virtual Apps and Desktops uses “Unicode Keyboard Layout Mapping” technology to make rule 2 from earlier in this post happen. Windows VDAs need to enable “Unicode Keyboard Layout Mapping” feature if users have key input issue when using a non-Windows version of Citrix Workspace app.
Configure in registry
Registry configuration is obsolete, but still support. Recommend to use group policy instead.
Add the following registries in Windows VDA to enable this feature:
HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\CtxKlMap\EnableKlMap value = DWORD 1
HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\CtxKlMap\DisableWindowHook value = DWORD 1
Please note, non-Windows versions of Citrix Workspace app will always follow rule 2 if the feature is enabled, even if the keyboard language is different between the client and the VDA. For example, Citrix Workspace app for Mac uses a U.S. English keyboard, but Windows VDA use a France keyboard layout. The key mapping will use the U.S. English keyboard. Mode 4 Synchronize VDA side keyboard with client keyboard dynamically in VDA session will always try to keep the keyboard layout as similar as possible between Citrix Workspace app and the VDA to reduce the key input issue.
Configure in Citrix group policy
After Windows VDA version 1912 CU2 and 2006, Linux VDA 2012, VDA configuration support Citrix Group Policy. Refer to CTX312404 for detail. Enable VDA dynamic client keyboard layout sync and IME improvement is below:
Recommend configuration
| Citrix Workspace app | Configuration |
| Citrix Workspace app for MAC | Sync mode 4 and Enable Unicode Keyboard Layout Mapping |
| Citrix Workspace app for Linux | Sync mode 1 key input follow rule 1 which means that key input is determined by VDA side keyboard layout. |
| Citrix Workspace app for Android | Sync mode 4 and Enable Unicode Keyboard Layout Mapping |
| Citrix Workspace app for iOS | Sync mode 4 and Enable Unicode Keyboard Layout Mapping |
| Citrix Workspace app for HTML5 | Sync mode 3 (default) and Enable Unicode Keyboard Layout Mapping |
Generic Client IME for Chinese, Japanese, and Korean (CJK) Users
The Generic Client IME feature provides a seamless input experience for CJK users if they want to use the client IME instead of the VDA side for a better user experience in the scenarios:
- Client use touch keyboard for example Microsoft Surface device.
- Use installed 3rd party IME in client side for published apps and desktops.
The Generic Client IME feature is enabled with keyboard synchronization mode 4. Citrix IME for CJK languages will be applied automatically in the VDA side when the user selects an IME in the client side.
Touch Keyboard in Windows 10
Windows 10 has touch keyboard to support tablet mode. Users can switch the keyboard layout from a touch keyboard using keyboard synchronization mode 4. Another setting is enables the keyboard to automatically pop up while opening the app with CWAs. Learn more about this configuration.
