Which online resources are good to learn how to type in TeX rather than LaTeX ? I am confused as to where to post this question given that most if not all code here is for LaTeX specific questions.
I want to know all the basic math commands for TeX rather than LaTeX; Sectioning and documentation commands etc ....
Thank you
\section{}which is ultimately defined in TeX, in a way that TeX can understand. I may be butchering this a bit, but basically the thing about TeX is you either have to build the sectioning commands yourself from scratch, or go and find some that someone else has done, the first port of call being LaTeX – Au101 Dec 06 '17 at 06:09plain-TeX, nottex-core. – Mico Dec 06 '17 at 06:23texdoc gentleat a command line prompt. that's also cited in the question linked by @CarLaTeX. – barbara beeton Dec 06 '17 at 17:42
