If connecting to Aqua Connect Terminal Server 3.x via RDC for Windows machines and your keyboard shortcuts are not working, here is what you do…

Open up RDC. At the bottom of the box, click on Options. It will extend the box to give you six menu tabs. Choose the one that says Local Resources.

In the keyboard section, the drop down menu will give you three choices. You can choose to apply the Windows key combinations on the Client (default), on the Remote Computer or only on the Remote Computer if it is full screen. Choose on the Remote Computer and hit connect.

Screenshots are from a Windows 7 client. Earlier versions of RDC have similar menu choices.
