The problem is that after the first <Tab> Curses::UI gives control of the terminal to Term::Complete. It acts directly on the terminal, and Curses::UI is not aware of what it does. It is not another perlio layer. Curses::UI is not aware of any keystrokes whilst in Term::Complete::Complete(). From the POD of Term::Complete:

The tty driver is put into raw mode and restored using an operating system specific command, in UNIX-like environments "stty".

So, Curses::UI and Term::Complete are not aware of each other. Term::Complete doesn't define up/down keys. It is tricky to integrate both...

With the snippet as provided, <Tab> must be pressed before attempting a completion; then you type the chars of a word you intend to complete. Subseqent <Tab> presses advance the completion until it is unambiguous. Then you press <Return> - completion done. Refresh the screen with ^L.

perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'
