A specific problem with altering the Mac command-key layout to behave like Windows

internationalizationkeyboardswitchingtext input

I want to change Command+Space combination to change keyboard layout to a Windows like Alt+Shift but the Lion's keyboard settings does not react when I assign that particular combination. It allows me to change it to a other combinations, however. I assume this is because Alt+Shift is already being used by some other program, but which one? How can I tell that and what can I do to override that setting?

I don't think you can use alt + shift for anything by itself. It is used for all kinds of special characters in combination with a letter key.
