On the right hand side - see attached screen, if you check one of those boxes you will see the channel box, layer editor, or I circled the one that will show a combination of the two.

As Fredrickkson says you might want to check out the basic documentation in Maya as it will help with that sort of thing (and save you writing ?!!! when someone tries to help out but doesn't give the answer you want straight away).

Mike mentioned where the channel box was in an answer to your question in your other thread btw.
