zle.yo contains the following.  We don't have the actual names for
all the widgets, which makes them hard to search for, but the actual
rule is very simple once you know it.  So while this isn't ideal I'm
not sure what we'd want to change.  Should we put some examples here of
the cases you're most likely to use, in particular .accept-line?

The standard widgets built into ZLE are listed in
ifzman(the section `Standard Widgets' below)\
ifnzman(noderef(Standard Widgets)).
Other built-in widgets can be defined by other modules (see
ifzman(zmanref(zshmodules))\
ifnzman(noderef(Zsh Modules))\
).  Each built-in widget has two names: its normal canonical name, and the
same name preceded by a `tt(.)'.  The `tt(.)' name is special: it can't be
rebound to a different widget.  This makes the widget available even when
its usual name has been redefined.
