That's not the right approach. Even if it might work, it will break
something else.

I can't figure out the correct command line. The terminfo man page
is a terrible read.

That's what I wanted to do. Actually I have similar mapping as you
do. But I can't figure out the right mapping for Meta-<arrow-keys>.

  # mappings like these work
  noremap <esc>[27;5;9~ :bnext!<cr>

  # the meta-<up> mapping does not work
  noremap <esc>[1;3A :bnext!<cr>

That was actually my question, what these mappings are.
