@smhigley what is happening here? It seems that focus is getting moved to the menu. Is this actually Fluent 2 behavior now?

[smhigley]

Hi! From your video, it appears that you switched Narrator into scan mode, which is why you cannot continue to type. This has nothing to do with Fluent, this is just how Windows screen readers work. In scan mode (or in VPC cursor in JAWS, or browse mode in NVDA), character keys activate specific navigation shortcuts, and are not used for typing. If you wish to type, you need to be in application mode / forms mode. The reason Narrator said "unavailable" is because there were no available navigable controls for the characters you pressed.

Hope that helps!

Hi @smhigley , thanks for the quick response, let me add more details about the repro steps:
Firstly, I set scan mode on when navigating to the combobox input area. When focusing on the input area, scan mode will close automatically (I didn't do it manually). If I start typing, (again I didn't change any Narrator scan mode manually), scan mode will automatically set as on and it prevent me from typing more characters into it.
Could you help confirm whether it is still expected behavior? If so, I can have this issue closed as expected. Thank you again!
