Misc

Image Preview

You can drop any image available in the folder of your notebook and type its filename in a new cell.

randompic.png

Reading and Writing Files

In principle, you can print the contents of any file located in the notebook's folder by typing its name without line breaks.

filename.txt

For writing, the process is the same, but the actual content goes on the next line:

filename.txt
Hello World

Shell

You can type commands directly into your system shell. The PATH is automatically imported from your terminal, and the working directory is set to NotebookDirectory[].

.sh
ls

LaTeX

There is a dedicated cell type solely to render LaTeX equations. You can still do it using Markdown, but if for some reason you have troubles mixing MD and TeX, here you go

.latex

\alpha^2 + \beta^2

This also does not require escaping TeX code with double slashes unlike other cell types.

Mermaid

Draw beautiful diagrams using code:

.mermaid
pie title NETFLIX
       "Time spent looking for movie" : 90
       "Time spent watching it" : 10

You can also apply custom styling:

.mermaid

%%{init: { 'theme': 'base', 'themeVariables': { 'primaryColor': '#ffcc00', 'edgeLabelBackground':'#ffffff', 'tertiaryColor': '#F0F0F0'}}}%%
