Demonstration of autocomplete
While I’ve been away on holiday Christoph has completed a demonstration version of TeX-command autocompletion. You can play with it here.
I’m very please with what he’s done, and am interested in producing an online version of Scott Pakin’s Comprehensive LaTeX symbol list (view as PDF), which has several thousand symbols.
In most situations, there will be a subset of relevant symbols, which will depend on what is being authored. Many symbols are required only in special areas.
