Yep it's a dog isn't it.
If you're using menus you can create a menu item with the Shift+Function key shortcut and that works.
You can also programmatically define a popup (DEFINE POPUP) with those short cuts - there's a way of having the popup active, as far as the shortcut keys go, and not have it visible to the user. Perhaps someone else can jump in here with some help on that front.
