Can you change the shader and font settings as a new default? I was wondering if you know how to change the default settings in Blender? When I change the "Viewport Shading" to render by pushing "Shift Z", then push "Shift Z" again to go back to "Solid", is it possible to have it go back to "Material" instead? I have tried looking up how to do this but nothing came up. 



Also when I load a font, the view always goes to "Short List". Is there a way to change the default setting to "Thumbnails" so that every time I open a font it stays on "Thumbnails"?



I know its probably not a big deal clicking one extra button but it would be a lot easier for my workflow. Would you know anything about this? Thanks!
For the first question about the keyboard shortcuts


Go to Blender User preferences window [Ctrl+Alt+U] under the "Input Tab"
Search for "Context toggle values" in the search field.
Scroll down to the "3D View" category
You should see three entries by default for [Z] [Alt+Z] and [Shift+Z]
key combinations.
Expand each of them and change the strings in the "Value" fields to whatever you want.
In you case change the [Shift+Z] to toggle between "MATERIAL" and "RENDERED"
