texmacs-vi-experiment VS SwiftLaTeX

> TeXmacs necessitates using its own interface (which lacks my vim keybindings and Emacs customizations)

TeXmacs's own interface is deeply customizable by the user via Scheme.

I think you can set it up to have vim keybindings---see experimental code at https://github.com/chxiaoxn/texmacs-vi-experiment and comments at http://forum.texmacs.cn/t/a-very-tiny-vim-in-texmacs/176 (I know that the lack of a block cursor has put off someone, but I did not find that comment in the brief search I did now).

There is a project for a replacement, called SwiftLaTeX, an online-based WYSIWYG editor for LaTeX documents, but the development is slow.

The screencast look good. For parallel/prior work in this sort of "live update" of the typeset document (and to learn from their experiences), you may also want to look at:

• SwiftLaTeX (https://github.com/SwiftLaTeX/SwiftLaTeX / https://www.swiftlatex.com/ — the cool demo that used to be on their site seems to be gone, but see HN discussion: https://news.ycombinator.com/item?id=21710105)

• BaKoMa TeX (http://www.bakoma-tex.com/) — its eponymous author Basil K. Malyshev passed away recently, but the product and page still exists for now

• VorTeX (see Pehong Chen's PhD thesis from 1988).
