PARAMETERS:
ptblItems - word(s) to lookup (first item is semi-colon delimited
list of external titles to check).
pCollection - collection pointer, needed to access word wheels.
pszDefaultTopic - default topic to jump to.
ppt - pointer to a point to center the window on. If NULL
then we will use the current mouse pointer position.
hWndParent - window to parent the "Topics Found" dialog/menu to.
If NULL, then use the active window.
bDialog - dialog based? If not, use a menu.
bKLink - is this a keyword lookup? if not, use the ALink list.
bTestMode - test existence only (dont' show a UI).
bSkipCurrent - skip the current URL in the returned list.
bAlwaysShowList - always show the hit list even if only one topic is found.
bAlphaSortHits - alpha sort the title list or not.
