I built a small physical keyboard for faster math symbol input

I’ve been using Typst for live math notes in class, or at least trying to.

The hardest part is not the syntax itself. It’s the tiny delays.

Some professors can write an equation with one hand and erase the previous line with the other. So, every second matters.

That made me think about math input speed in a very practical way.

So I built a compact physical keyboard for mathematical symbols.

It has common Greek, mathematical, and scientific symbols printed directly on the keys, with blue and gray symbol layers. When writing in Typst, I can insert symbols with key combinations instead of typing the entire keyword.

It is definitely niche, but it is made for exactly this kind of workflow: live notes, technical writing, and reducing the small interruptions that break concentration.

I’m curious what other Typst users think about this kind of setup.
