How do you view the selected face texture in Valve Hammer Editor?

In Valve Hammer Editor, you can view the selected face texture by selecting the face in the 3D view and then checking the "Texture Application" window. This window displays the current texture applied to the selected face, allowing you to see its properties and make any adjustments as needed. Additionally, you can use the "Texture Browser" to browse and apply different textures to your selected face. To preview the texture in the 3D view, you can also toggle the texture display mode.
