I stumbled upon the following fragment of documentation, buried in the standard library.
Note that source locations have auto-complete for the path component.

Since the std:// scheme is being sunset (usethesource/rascal#2828) and I cannot find a mention of tab-completion of source locations in the REPL, this should probably be documented somewhere else.
