I am using 12.04 and in my work we connect to a Citrix XenDesktop. I've installed Citrix Receiver, using this link and it all works perfectly.

But, I have a problem. Alt+Tab doesn't work in full screen mode. There are several adjustments you can choose when login in, with the Settings "button" up in the right corner. (Sorry, I couldn't post an image because I'm new.)

I like to work with 95% full screen, with the windows key combination in "full screen mode only". This allows me to use the windows combinations when a work in full screen, inside the remote computer (inside Citrix).

I can Alt+Tab past the "Citrix computer" when I put it down to 95%. It also allows me to use the "Ubuntu menu" on the left side. But I really can't make this work in Ubuntu.

I've tried to put the windows key combination to "remote server only" and yes, it works inside the server, but also only there and the Ubuntu menu stops working. (in example print Screen. I am using this for documentation.)

When I try to Tab from one place to another, even when Citrix isn't in full mode, if I stop there and the continue "tabbing" it continues inside Citrix.

I want to use windows key combination, but only in full screen mode. Does anyone have a solution to fix in another way?
