How to forward keyboard shortcuts to the remote machine sessions in Sysinternals Remote Desktop Connection Manager?

Since shortly, I’m using Remote Desktop Connection Manager from Sysinternals.
I’ve added several remote desktop connections and I’m connecting to several remote computers in that way.

When I do that, I can see the taskbar, open programs via the “Start” button, …, but when I press a keyboard shortcut, like Alt+Tab, this is not performed inside the remote desktop session, but on my main computer, simply going to another program on my main computer.

Is there some way to make the Alt+Tab shortcut working inside the remote desktop sessions of the Sysinternals Remote Desktop Connection Manager?

The reason for this question: I have launched msvsmon32, the remote debugger, on those remote computers. That remote debugger is still running but I’d like to change its configuration. For that, I need to show the remote debugger’s UI which is not accessible via Taskbar or Task Manager (only via Alt+Tab as far as I know).
