vimtutor (type it in the command line)
after that: edit a couple of documents, write down what you want shortcuts to and learn those. Target practice allows you to learn vim quite quick.
Haven't used it for several years though, so no idea if the WSYIWYG is still up and running.
- LyX: full Latex compiled, and Mix between WYSIWYG and Latex Script. Mainly use to create Latex Document
- Mathcha: can export some parts to Latex (mostly Math mode) but does not guarantee to compile, a full WYSIWYG editor. The goal to just create Document without constraints to Latex format
No, "Africa" is far too huge and varied to generalize about like that. Plenty of African countries have reasonable mobile infrastructure, and low enough costs.
$ apt install lyx

Need to get 216 MB of archives.
(This is coming from nothing, LaTeX isn't installed.) At 5Mb/s, that's about 6 minutes. That's not unreasonable for a one-off installation, especially in a country where these speeds are normal. (And 5Mb/s is slow: https://www.speedtest.net/global-index .)My friend is a math professor, uses tablets with stylus.
I'd use Emacs org-mode now unless the Wiki made was needed to work on with others.
- Export to Latex (Mostly for Math Mode, and does not guarantee compiled in complicated case)
- Tikz (for Diagram)
- MathMl (Math Mode only)
- SVG/PNG (Math Mode and Diagram only)
- Save as Html (.zip file)
- Save as PDF (currently supported on Desktop version), but you can use Browser Print and save as PDF
2. Sorry, I don't have clear Road map, mainly I'm working on to add more features specifically on Math (for example Z Specification)
3. Unfortunately there is no one-time payment license now.
You can try out Mathcha[1] which is built to help people without knowing of Latex can easily write down Note (with rich Mathematics symbols/layouts) and it also provide basic Drawing and basic Function Plotting (The Drawing Part no way compare to Inkscape, but hey! you can type Math on Drawing on Mathcha) in single Editor.
Please note that I don't want to tout and advertise Mathcha here, the point is to provide another option for people to try out (I will not say it will provide faster or more powerful than Vim+Latex)
