4459 * TREEVIEW_ProcessLetterKeys
4461 * Processes keyboard messages generated by pressing the letter keys
4463 * What this does is perform a case insensitive search from the
4464 * current position with the following quirks:
4465 * - If two chars or more are pressed in quick succession we search
4466 * for the corresponding string (e.g. 'abc').
4467 * - If there is a delay we wipe away the current search string and
4468 * restart with just that char.
4469 * - If the user keeps pressing the same character, whether slowly or
4470 * fast, so that the search string is entirely composed of this
4471 * character ('aaaaa' for instance), then we search for first item
4472 * that starting with that character.
4473 * - If the user types the above character in quick succession, then
4474 * we must also search for the corresponding string ('aaaaa'), and
4475 * go to that string if there is a match.
4483 * - The current implementation has a list of characters it will
4484 * accept and it ignores everything else. In particular it will
4485 * ignore accentuated characters which seems to match what
4486 * Windows does. But I'm not sure it makes sense to follow
4488 * - We don't sound a beep when the search fails.
4489 * - The search should start from the focused item, not from the selected
4490 * item. One reason for this is to allow for multiple selections in trees.
4491 * But currently infoPtr->focusedItem does not seem very usable.
