moderated Re: Font changes, etc. setting
What follows is both lecture and attempt to help, and the lecture is a part of that attempt.
From what you've written, I am guessing that you may have recently gone blind and be very new to JAWS or any screen reader. I have some "rules" you need to follow that will make your life much, much easier when dealing with all things computer related under Windows 10, or any operating system really.
Rule 1. When you are trying to get a specific thing to occur, particularly if uncertain, take the time to think about what should be controlling that specific thing. You gave an excellent example, getting Word Count or determining the font currently in use. There will be three levels that will always be involved for you to think about, but only one of the three is going to be responsible for "the thing" no matter what it is.
a) Windows 10
b) Your Screen Reader
c) Your application program (word processor, web browser, software updater utility, etc., etc., etc.)
In this case, before I answer (and I'm sure you probably know it now), which of those three is most likely to handle the word count and font information: the application program, in this case MS-Word. So if you're looking for documentation regarding keyboard shortcuts to get this information, you'd want to do web searches on Microsoft Word Keyboard Shortcuts. And Microsoft is great about documenting keyboard shortcuts for every program it produces in detail. Click through on this link for a DuckDuckGo.com web search on MS-Word Keyboard Shortcuts and I will be shocked if the first result for you isn't the same as it is for me:
Keyboard shortcuts in Word - Office Support
which has the magic shortcut: CTRL+SHIFT+G for bringing up the Word Count dialog.
and/or the Microsoft Office Accessibility Discussion Group:
