4424 * TREEVIEW_ProcessLetterKeys
4426 * Processes keyboard messages generated by pressing the letter keys
4428 * What this does is perform a case insensitive search from the
4429 * current position with the following quirks:
4430 * - If two chars or more are pressed in quick succession we search
4431 * for the corresponding string (e.g. 'abc').
4432 * - If there is a delay we wipe away the current search string and
4433 * restart with just that char.
4434 * - If the user keeps pressing the same character, whether slowly or
4435 * fast, so that the search string is entirely composed of this
4436 * character ('aaaaa' for instance), then we search for first item
4437 * that starting with that character.
4438 * - If the user types the above character in quick succession, then
4439 * we must also search for the corresponding string ('aaaaa'), and
4440 * go to that string if there is a match.
4448 * - The current implementation has a list of characters it will
4449 * accept and it ignores everything else. In particular it will
4450 * ignore accentuated characters which seems to match what
4451 * Windows does. But I'm not sure it makes sense to follow
4453 * - We don't sound a beep when the search fails.
4454 * - The search should start from the focused item, not from the selected
4455 * item. One reason for this is to allow for multiple selections in trees.
4456 * But currently infoPtr->focusedItem does not seem very usable.
