There are many ways to maximize JupyterLab's utility. In this chapter, we saw the operations that can be accomplished using the Code Console and the Terminal. The Code Console uses the kernel for code completion and tooltips. The Terminal provides direct shell access from JupyterLab. We also looked at more advanced settings, such as the highlighting syntax, indent settings, keystroke mapping, and theme selection. 

In the next chapter, we will discuss how to add, manage, and build extensions.
