Sorry for the late answer.

You did not find an answer to that problem, because your problem is
wrong (but admittedly badly document).

the [\] (backslash) key actually creates an "hybrid" structure, which
can be resolved to one of:

  -- an active latex shortcut (where latex shortcuts are specific
     class of shortcuts used in texmacs) (e.g. maketitle)

  -- a function application (apply "func" ...) where 'func' is the
     name of a function defined in the current context (e.g. index).

  -- a macro expansion (expand "macro" ...) where 'macro' is the name
     of a macro defined in the current context  (e.g. section)

  -- a couple of other special cases

This general does not include _typesetter primitives_ like "rsub",
which must be inserted from the menu or specific shortcuts (like
[underscore] in math context).

The behaviour you expect with [tab] is only applicable when the name
you have typed is bound to a function or a macro in the current
context.
