Changing keyboard input language on Mac OSX How do I change (switch) the input language in Mac OSX  (English->Russian->Hebrew).
In Windows it is done by pressing alt-shift. 
What is the equivalent in OSX ?
Go to  > System Preferences > Language &amp; Text > Input Sources.

Make sure an entry for each of 'English', 'Hebrew' and 'Russian' are checked. (I don't know which encoding you'll choose, e.g. 'Hebrew' or 'Hebrew - QWERTY'). Also ensure the uppermost box, 'Keyboard &amp; Character Viewer' is checked.

Now you'll have something that looks like this:



You can select your language with the mouse or you can activate keyboard shortcuts, as seen below:



Both these keyboard shortcuts are already taken by other functions. These are functions that I use far more frequently than when I want to, in my case, shift between 'Australian' and 'Thai'. So in my case it's not worth making a keyboard shortcut to switch languages. This may be different for you however.

If you wish to activate, say, ⌘Space, you'll first need to disown that from whatever is currently using it. In my case ⌘Space opens a Spotlight search box and I use this all the time.
