4388 * TREEVIEW_ProcessLetterKeys
4390 * Processes keyboard messages generated by pressing the letter keys
4392 * What this does is perform a case insensitive search from the
4393 * current position with the following quirks:
4394 * - If two chars or more are pressed in quick succession we search
4395 * for the corresponding string (e.g. 'abc').
4396 * - If there is a delay we wipe away the current search string and
4397 * restart with just that char.
4398 * - If the user keeps pressing the same character, whether slowly or
4399 * fast, so that the search string is entirely composed of this
4400 * character ('aaaaa' for instance), then we search for first item
4401 * that starting with that character.
4402 * - If the user types the above character in quick succession, then
4403 * we must also search for the corresponding string ('aaaaa'), and
4404 * go to that string if there is a match.
4412 * - The current implementation has a list of characters it will
4413 * accept and it ignores everything else. In particular it will
4414 * ignore accentuated characters which seems to match what
4415 * Windows does. But I'm not sure it makes sense to follow
4417 * - We don't sound a beep when the search fails.
4418 * - The search should start from the focused item, not from the selected
4419 * item. One reason for this is to allow for multiple selections in trees.
4420 * But currently infoPtr->focusedItem does not seem very usable.
