Getting Started

There are three buttons running alongside the left side of your screen.

Selecting the folder icon will display all the projects you’ve worked on.

The stop button gives you the ability to quickly close all open tabs or shut down any running kernels or terminals.

The table of contents button is designed to help users navigate through their notebooks more efficiently, especially when working with lengthy or complex notebooks. When you click on the TOC button, it displays a panel that lists all the sections of your notebook based on the headings you've used in Markdown cells. Here's a breakdown of its functionality:

1. Structure Overview: The TOC provides an organized overview of your notebook's structure, listing headings and subheadings in a hierarchical manner. This makes it easier to understand the flow of the notebook at a glance.
2. Easy Navigation: By clicking on an item in the table of contents, JupyterLab automatically scrolls to the corresponding section in the notebook. This is particularly useful for quickly moving between different parts of the notebook without having to scroll manually.
3. Dynamic Update: The TOC updates dynamically as you add, remove, or edit headings in your notebook. This means that the TOC always reflects the current structure of the notebook, helping you keep track of content changes.

At the top of your notebook, there’s a second set of buttons to assist you. Let’s take a look.

Worried auto-save hasn’t captured your latest thought? You can force a save by click the floppy disk in the top left.

Add a cell directly beneath the last one you were typing in.

Select the scissors to quickly delete the cell you have highlighted.

Use this to copy the content from a highlighted cell.

Use this to paste content copied using the previously discussed button.

Run the code in the selected cells and advance to a new cell.

Pause any running kernels so you can make edits.

<aside> 💡 Jaxon Tip: In computing, a kernel is a fundamental component of an operating system. It acts as a bridge between the hardware and software layers of a computer system. The kernel is responsible for managing system resources, such as memory, CPU time, disk space, and peripheral devices, and it provides essential services to other parts of the operating system and to user programs.

Restart the kernel. This starts the process from the stop point.

Restart the kernel and run all cells. This starts the process from the beginning.

Select the desired cell type. For more information on what each does, see Cell Types

There’s another set of buttons within the notebook for you to use. These are found on the far right of a cell. Let’s take a look.

Use these two buttons to move the selected cell up or down.

Finally, if you right click on any cell, you’ll open the below menu which gives you another option for enacting basic controls.
