keys act on the focused pane, deletes ask y/N in place

dd, x, i, R, s, y and :mv used the open document whenever one was open,
so walking the list and pressing dd deleted the document beside it. They
now act on the row under the cursor while the list has focus. Deletes ask
an in-app y/N naming the node instead of confirm(), and the board no
longer lets tree keys through to the hidden list.
