LaTeX is one of the most important tools that I properly started using regularly whilst at unviersity. It's the typesetting tool in CS, and you can get some really beautiful results from it. There's great tooling for IDEs like IntelliJ (https://github.com/Ruben-Sten/TeXiFy-IDEA https://github.com/Ruben-Sten/TeXiFy-IDEA), it makes managing references (using BibTeX) much less of a chore, there are tons of high-quality packages that do pretty much anything you could think of and there's an excellent community on e.g. TeX.SE to provide support. It's free software, the results are better than Word and it's much less painful to use than an unpredictable WYSIWYG editor. I've used it in industry to write security audit reports and more recently as part of my dissertation. My only regret is not discovering LaTeX earlier and using it more.
