Digital note-taking in STEM often forces a compromise between speed and structure. Handwritten notes are fast but unsearchable; standard LaTeX is structured but far too verbose for live lectures.
To bridge this gap, I have configured a Visual Studio Code environment optimized for zero-latency typing.
The Stack
My workflow relies on two specific extensions to transform VS Code from a code editor into a rapid note-taking engine:
- LaTeX Workshop: The core engine for syntax highlighting, linting, and real-time compilation.
- HyperSnips: A powerful snippet engine that uses Regular Expressions (RegEx) for context-aware expansion.
The Accelerator: HyperSnips
Standard VS Code snippets are insufficient for math because they require a trigger word followed by a Tab press. This adds friction.
I use HyperSnips to implement “auto-expanding” snippets. The key differentiator is context awareness: my snippets behave differently depending on where my cursor is located.
- Global Context: Standard text expands normally.
- Math Context: Inside delimiters (e.g.,
$ ... $), specific key combinations trigger immediate LaTeX expansion without hitting tab.
Example: Instant Fractions
Instead of typing the verbose \frac{}{} and manually navigating cursor positions, I simply type //.
The engine detects that I am inside a math block and instantly expands it into a fraction object, placing my cursor in the numerator automatically.
// latex.hsnips
// Only trigger inside math zones
context math(context)
snippet // "Fraction" A
\frac{$1}{$2}$0

This configuration removes the mechanical friction of LaTeX. I am no longer thinking about syntax, backslashes, or compilation; I am simply transcribing complex logic in real-time.
The result is a set of notes that are typeset professionally, searchable instantly, and produced without ever slowing down the lecture.
Why use this?
It eliminates friction. I can focus on the logic of the lecture rather than the syntax of the document.
