I had to change <Meta-.> to <Meta-period> and then to <Alt-period>
(the latter is probably a misconiguration at this end, but the first
may not be).
I'm very used to some other readline conventions such as Meta-. being
yank-last-arg and C-r being reverse-search-history and some
others. Would these be easy to add to your extension? (I know next to
nothing about Tkinter).

I think I'd settle for the completions being selected from the words
known to the Python shell, if that helps.
While we're on the subject of idle, is there any easy (preferably one
or two keystrokes) that way to import/reload the module being edited
into the Python shell and bring said shell to the front for instant
interactive play? That'd be übercool.
