List Ahoy:
As the subject line suggests, this report is not of a secretive bug, discovered by happenstance.
Under LO 4.3.6.2, and 4.0.6.2 (portable), Curtains 7/64 bit, on the "Tools" pull-down menu, there are 2 (count them: two) entries that start with "A":
"AutoCorrect Options" and "Address Book Source".
Although the initial A is underlined in both cases, neither can be selected by keystroke, due to the obvious ambiguity.
As far as I can tell, only the rodent can advance the user in this context.
OO 3.2.1 and 4.1.1 do not have the "Address Book Source" item on their "Tools" menus, and so a simple A works there for AutoCorrect. That leads one to presume that the LO Address Book item was spatchcocked onto pre-existing OO code, without much thought being given.
It is hard to imagine that this defect, of long-standing, is unknown in higher circles, and so the presumption must be that there is not much interest in it, at least not as contrasted with more urgent concerns.
I propose posting a bug, however futile, for form's sake, and am soliciting any comments that might rescue me from a potential embarrassment.
