" The following variable configures the way |tlib#input#ListD()| works.
" In this example, we allow selection of multiple items (we could also
" allow only a single choice and make |tlib#input#ListD()| work on the
" indices, not the items).
"
" We also set a prompt that will be displayed in the command area.
"
" By default, |tlib#input#ListD()| will automatically select an item if
" there is only one item left matching the filter. In this example, we
" disable this feature.
"
" For demonstration purposes, we also define a key handler that prints
" the selected items.
