I need use the key combinations Ctrl-Alt-Left Arrow and Ctrl-Alt-Right Arrow in an application on my computer. When I use Remote Desktop to connect to that computer, either the Remote Desktop Client (mstsc.exe) or the RDP server implementation swallow these key combinations. The combos appear to be reserved to the Remote Desktop, although they don't seem to be doing anything.

Is there a way (supported or not) to disable this behavior so that the key combinations are sent to my application?

For using CtrlAlt+ in Far Manager I used the following AutoHotKey script:

!^Right::
send ^+{F9}
return

!^Left::
send ^+{F8}
return

… where under CtrlShiftF8/F9 I have Far macros which do the same as when pressing CtrlAlt+.

This workaround only works if in Properties, the connection option Keyboard is set to "On this computer".

I'm marking this as the accepted answer because I ended up doing something similar: I, too, have an AutoHotKey script on my host computer that captures and translates the key combo to a different one; then I have a second AutoHotKey script on the remote computer that translates it back to the original key combo. –  Fabian Schmied Oct 17 '12 at 9:00

Make sure you have the Keyboard settings set to something appropriate for how you use RDP. Have a look in the options for your RDP connection, on the Local Resources Tab.

If you always have the connection full screen then set it to "Only when using the full screen" but if you don't use RDP in full screen then set it to "On the remote computer."

This does not solve the issue. I always have the connection full screen, and the "Local Resources/Keyboard" settings are set to "Only when using the full screen". This means I can use Alt-Tab and the like, but I still canot use Ctrl-Alt-Left Arrow or Ctrl-Alt-Right Arrow. –  Fabian Schmied Aug 25 '11 at 13:34
