29 * We use callbackMask to keep track of fields to be updated.
32 * missing notifications: NM_SETCURSOR, TVN_GETINFOTIP, TVN_KEYDOWN,

35 * missing styles: TVS_FULLROWSELECT, TVS_INFOTIP, TVS_RTLREADING,
37 * missing item styles: TVIS_CUT, TVIS_EXPANDPARTIAL
39 * Make the insertion mark look right.
40 * Scroll (instead of repaint) as much as possible.

4320 * TREEVIEW_ProcessLetterKeys
4322 * Processes keyboard messages generated by pressing the letter keys
4324 * What this does is perform a case insensitive search from the
4325 * current position with the following quirks:
4326 * - If two chars or more are pressed in quick succession we search
4327 * for the corresponding string (e.g. 'abc').
4328 * - If there is a delay we wipe away the current search string and
4329 * restart with just that char.
4330 * - If the user keeps pressing the same character, whether slowly or
4331 * fast, so that the search string is entirely composed of this
4332 * character ('aaaaa' for instance), then we search for first item
4333 * that starting with that character.
4334 * - If the user types the above character in quick succession, then
4335 * we must also search for the corresponding string ('aaaaa'), and
4336 * go to that string if there is a match.
4344 * - The current implementation has a list of characters it will
4345 * accept and it ignores averything else. In particular it will
4346 * ignore accentuated characters which seems to match what
4347 * Windows does. But I'm not sure it makes sense to follow
4349 * - We don't sound a beep when the search fails.
4350 * - The search should start from the focused item, not from the selected
4351 * item. One reason for this is to allow for multiple selections in trees.
4352 * But currently infoPtr->focusedItem does not seem very usable.
