FT -- mustoverridable keyword

The help of MS has various kinds of errors. Of course, I still think that there are few errors after all, but you have to be laughed at by some strange things.

Today, I suddenly found a new keyword, which looks like VB. NET, and is obviously unauthenticated ented: mustoverridable. Why? Believe it? In vs. net, press Alt-H, I, and mustoverridable to see what happened? I don't know if the same result is displayed on your machine: "mustoverridable keyword ". Novelty? The difference between mustoverride and notoverridable is as follows. Perhaps it was inspired by the combination of Chinese and English into Chinglish. The author of the document invented a mustoverridable. The invention will be invented, followed by a "keyword "! Really bad! I thought I found the new world ......
