4575 * - If two chars or more are pressed in quick succession we search
4576 * for the corresponding string (e.g. 'abc').
4577 * - If there is a delay we wipe away the current search string and
4578 * restart with just that char.
4579 * - If the user keeps pressing the same character, whether slowly or
4580 * fast, so that the search string is entirely composed of this
4581 * character ('aaaaa' for instance), then we search for first item
4582 * that starting with that character.
4583 * - If the user types the above character in quick succession, then
4584 * we must also search for the corresponding string ('aaaaa'), and
4585 * go to that string if there is a match.
4593 * - The current implementation has a list of characters it will
4594 * accept and it ignores everything else. In particular it will
4595 * ignore accentuated characters which seems to match what
4596 * Windows does. But I'm not sure it makes sense to follow
4598 * - We don't sound a beep when the search fails.
4599 * - The search should start from the focused item, not from the selected
4600 * item. One reason for this is to allow for multiple selections in trees.
