Window Tabs ?

[haikuman]

Well I was not very clear was I.... and I am a big dummy *(:>*

I went to Pref's>> Displays>> changed resolution to stretched so I could grab the tab and reduce the iTunes window size. It had self expanded so I could not grab the corner and reduce the window sizing.
The corner tab was below the dock.

Question is and should be How do I manually or by key strokes reduce the window size to various sizes...
