Windows shortcut keys pass-through with Citrix client

IT had us switch from Windows Terminal Services to Citrix recently and feeling a bit frustrated with Citrix client not passing through the Windows keys (like ALT+Tab or Win+R) but only in full-screen.

Citrix ICA File Creator is very handy in creating .ica shortcut files pretty much like you would rdp connection files with Remote Desktop Connection client.

Once you create the .ica file you can edit it with a text editor (.ini file structure) to add the setting to always pass-through the Windows keys to the remote session:
[WFClient] 
TransparentKeyPassthrough=Remote
From what I read the possible values are Remote, Local and FullScreenOnly. Personally I like the Remote option, that sends the keys over when the Citrix client window is the active application.

With Citrix Receiver 3.2 I cannot seem to change this in the plugin settings, but this Windows registry key should do it - see http://support.citrix.com/proddocs/topic/ica-settings/ica-settings-transparentkeypassthrough.html

Windows 7 x64 Enterprise edition – for all users:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client\
Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\
Keyboard\TransparentKeyPassthrough = Remote
