Maths undergrad and olympiad trainee. I take all my notes in Obsidian with Vim keys and LaTeX, and I build the plugins I need along the way: text objects, jumps and editing commands for maths. Feedback and issues welcome on GitHub.
Vim text objects, jumps and editing commands for LaTeX maths, environments, brackets and commands.
Spelling keys for Vim mode (]s [s z= zg zw), numbers that count what gj and gk move by on wrapped lines, and Ctrl-N / Ctrl-P in menus.
Jump anywhere on screen in Vim mode: type a few characters, press the label. Works inside rendered LaTeX maths too.
Zathura's keys in the PDF view: J/K pages, gg/G, zoom, marks, search, dark recolor, a status bar and last-page memory.
