Where can I find the Texture tab? I have recently downloaded blender 2.72b and am having trouble finding how to texture objects. I have tried to look up videos about it but they all seem to have the Texture tab, in the Properties panel, whereas mine is off-screen and I can't get it on screen. 

How can I get to this tab?
The Texture tab can be found in the Properties panel, but in the default state of the interface, it may not be accessible; What you need to do is to simply hover your mouse over the list of tabs in this panel, in the top, and use the Mouse Wheel to either scroll, on press it's button and drag.
