Control-Alt escape from remote machine context

Hi,
On what type of session have you tried this?

A remote desktop (RDP) session.

Hi,
Would you mind to verify in the Local Resources tab page if the Keyboard combobox value is set to "On the remote computer"?

Yes, it is.
Here is the experience I seek: the Alt+Tab combination switches tasks inside the remote machine. In order to "get out" into the local machine, one can press Control+Alt (and then Alt+Tab works locally).

Hi,
If I understand correctly, we should ask this to Microsoft. They do the RDP client and ActiveX. I don't think I can do anything for that. Let me know if I'm wrong and you see a solution?

Well, in essence you are correct.
However, I did find a clue for something similar: CTRL+ALT+RIGHT/LEFT, which is supported by the TS ActiveX control:

I added this to our todo, I will try to do some test and see if we can implement this. This won't be in the next version (we expect to release it in the next few weeks).

Thank you for your help.
