Hi, when Alt+Shift is being pressed on Windows as Across Server, send Ctrl+Space to Android client. Alt+Shift is keyboard shortcut for change input language on Windows, Ctrl+Space is keyboard shortcut for change input language on Android. Of course, may be some config file would be required for such remap; Something like remap.cfg Alt+Shift=Ctrl+Space; change input language Ctrl+H=Win+Esc; go to android home screen CapsLock=LeftClick; send mouse click at current coordinates Keyboard remap on android is possible by some applications in GooglePlay but it requires root access and also each remap requires phone restarts. But your application is bluetooth keyboard emulator and may be can do such remap on the fly and without root access.
