I wasn't going to respond to your last message because I hoped that someone who speaks with the authority of a developer would respond. They still may. I wouldn't have continued to answer when it became clear that you wouldn't believe what I said if we were not on the list. But this is an NVDA list with users who range from beginner to advanced. I shall therefore quote from the manual. Maybe you will think the manual writers know what they are talking about if you insist that I don't.
I tried using control f during the debate to make absolutely sure it doesn't work in browse mode. It doesn't. I wasn't moved to the result I was looking for.
From the manual:
Pops up a dialog in which you can type some text to find in the current document
Finds the next occurrence of the text in the document that you previously searched for
Finds the previous occurrence of the text in the document you previously searched for
If control f could be used, don't you think it would have been stated in the manual and would be the command given? Why give a command different from the general one used in Windows and Windows programs and a command that requires that an extra key be pressed when simply control f can be used.
