4458 * TREEVIEW_ProcessLetterKeys
4460 * Processes keyboard messages generated by pressing the letter keys
4462 * What this does is perform a case insensitive search from the
4463 * current position with the following quirks:
4464 * - If two chars or more are pressed in quick succession we search
4465 * for the corresponding string (e.g. 'abc').
4466 * - If there is a delay we wipe away the current search string and
4467 * restart with just that char.
4468 * - If the user keeps pressing the same character, whether slowly or
4469 * fast, so that the search string is entirely composed of this
4470 * character ('aaaaa' for instance), then we search for first item
4471 * that starting with that character.
4472 * - If the user types the above character in quick succession, then
4473 * we must also search for the corresponding string ('aaaaa'), and
4474 * go to that string if there is a match.
4482 * - The current implementation has a list of characters it will
4483 * accept and it ignores everything else. In particular it will
4484 * ignore accentuated characters which seems to match what
4485 * Windows does. But I'm not sure it makes sense to follow
4487 * - We don't sound a beep when the search fails.
4488 * - The search should start from the focused item, not from the selected
4489 * item. One reason for this is to allow for multiple selections in trees.
4490 * But currently infoPtr->focusedItem does not seem very usable.
