Both dialog and cdk have limited ability to use the tab-key for traversing
between widgets.  However - that is "limited", and it's easy to conceive
of user interfaces which require something more sophisticated (or specialized).

Likewise, the form- and menu-libraries in ncurses address a certain style.
So... if you really know what you want, and spend time on it, low-level
ncurses works well.  But if you want something quick which follows one of
the respective libraries' limitations, then the libraries are a good choice.
