user. displays methods and fields of User), keywords, built-in types, and standard library modules (database, csv, dataframe, tensor, statistics, algebra, crypto, regex, datetime, encoding, net, http, reui).
- Hover Tooltips: Rich markdown hover tooltips showing static types, symbol signatures, and documentation.
- Go to Definition: Jump directly to declarations (
F12).
