OS X per windows language

Question

Windows (and Linux) users are used to the fact that after switching the typing language, the change affects only the active window. This way, one can type in English in the browser window, and Spanish in the IM window, without having to switch language after each Alt-Tab.

Is there a similar setting for OS X?

Answer 1

Yes there is. Under Snow Leopard 10.6 :

System Preferences > Language & Text > Input Sources

you should see the radio option "Allow a different one for each document". Select that instead of "Use the same one for all documents".
