# FAQ overflow

#### QUESTION

This question led to a new package:
macros2e

Is there a place where I can find a reference of LaTeX internal commands? For example, just a few months ago I saw an answer using \@for and today I found about \@star@or@long. Is there a place where these are documented? How did people using these commands learn about them?

I now compiled such a document listing all internal macros of LaTeX2e which are also useful for package authors. The work title is "List of internal LaTeX2e Macros useful to Package Authors" and I'm planning to release it on CTAN 'soon' (e.g. as 'macros2e') when its out of the beta stage.
