And that's it. This thimble-sized mug taught a majority of the basic tools that will continue to be used in future 3D modeling projects. Some of those tools are:
File operations such as saving and creating new directories
Adding basic objects (Shift + A)
View rotation with the number pad
Scene navigation with the middle-button on the mouse
Wireframe and Solid view modes (Z)
Selection operations such as Circle (C) and Box (B) select
Manipulation operations such as Grab/Move (G), Rotate (R), and Scale (S)
Edit mode (Tab) for manipulation of the individual elements that make up a shape
The Extrude (E) operation
The loop-cut (Ctrl + R) operation
Object modifiers such as Multiresolution and Boolean operations
Exporting STLs for print
That is a long list. Have a drink.
The next chapter will teach a different tool set for modeling similar objects using lines and lathes, but the skills of vertex selection and manipulation learned in this chapter will still come in useful!
