How do I add a tag to a question that I asked? [duplicate]

Question

I am wondering how I can add another tag to a question that I asked.

More specifically, I asked this question and tagged it with the tag winapi. After submitting the question, I realized that there was the tag win32api as well which seemed to suit my question. So I tried to edit the question in order to add the win32api tag. After re-submitting the question however, the new tag didn't display. So, is this behaviour expected?

Answer 1

win32api is a synonym of winapi, which means the former is automatically replaced with the latter. (It also means, the two tags are equivalent, so there's no need to tag your question with both.)
