I'm a Softimage and Cinema 4d user and I'm relatively new to Maya. I will give all of you some headaches with my newbie questions so sorry for this

In softimage there is feature called cluster matarial for multi texturing a mesh's desired parts. In short, select some polygons and drag and drop a matarial into this polygon selection and you have a cluster matarial.
I excatly can do this in Maya and everyting is ok from here but how can I see what matarial assigned to what polygon selection later on? How can I reselect this polygon selection again?
Any advice is greatly appreciated
Thanks
