Switch to Next Desktop     -> Ctrl+Alt+Right
Window to Next Desktop     -> Ctrl+Alt+Shift+Right
Switch to Previous Desktop -> Ctrl+Alt+Left
Window to Previous Desktop -> Ctrl+Alt+Shift+Left

Notes:

I am not sure whether to use

Switch to Next Desktop     -> Ctrl+Alt+Shift+Right
Window to Next Desktop     -> Ctrl+Alt+Right
Switch to Previous Desktop -> Ctrl+Alt+Shift+Left
Window to Previous Desktop -> Ctrl+Alt+Left

or

Switch to Next Desktop     -> Ctrl+Alt+Right
Window to Next Desktop     -> Ctrl+Alt+Shift+Right
Switch to Previous Desktop -> Ctrl+Alt+Left
Window to Previous Desktop -> Ctrl+Alt+Shift+Left

Afterwards see which operation you do most and then assign Ctrl+Alt+<Right|Left> to that as it involves pressing less number of keys.
