I have two monitors, will a full-screen remote desktop session running on one of them, and regular windows programs running on the other.
When one of the other programs have focus, I can Alt+Tab between the windows normally, and one of the choices that I can Alt+Tab to is the remote desktop.
Once I switch to the remote desktop, the keyboard is "trapped" by the remote desktop, so that further Alt+Tab's switch between the programs open in the remote desktop.
Is there a keyboard shortcut that "un-traps" the keyboard while the remote desktop has the focus, so that a subsequent Alt+Tab will switch to one of the programs on my other monitor?
(I am used to VirtualBox virtual machines where there is a key (usually Right Ctrl) which does precisely that, i.e. un-traps the keyboard from the VM.)
