I guess, common functionality in different module have different SlotID, but they have the same WhichID which match this functionality. So we convert it to WhichID, and the program know which functionality is it. Right? > > As an example, we have a slotid that can be used to change the font size > of a text, SID_ATTR_FONT_SIZE.

I believe it helps to me to understand the relationship of the SlotID and WhichID.
