341 * - If two chars or more are pressed in quick succession we search
342 * for the corresponding string (e.g. 'abc').
343 * - If there is a delay we wipe away the current search string and
344 * restart with just that char.
345 * - If the user keeps pressing the same character, whether slowly or
346 * fast, so that the search string is entirely composed of this
347 * character ('aaaaa' for instance), then we search for first item
348 * that starting with that character.
349 * - If the user types the above character in quick succession, then
350 * we must also search for the corresponding string ('aaaaa'), and
351 * go to that string if there is a match.
359 * - The current implementation has a list of characters it will
360 * accept and it ignores averything else. In particular it will
361 * ignore accentuated characters which seems to match what
362 * Windows does. But I'm not sure it makes sense to follow
364 * - We don't sound a beep when the search fails.
