Even that wouldn't cause you to lose your settings when switching to another 
screen window. The "Save on Exit" feature means that your current settings will 
be automatically saved to disk when you leave the preferences menu. This means 
that you won't lose them if you restart brltty.

I don't use Windows, so I'm not very familiar with JAWS. In particular, I don't 
know what a JAWS Video Intercept is.

Insofar as brltty is concerned, it runs on many platforms. Each platform has 
its own way of reading what's on the screen, supporting virtual keyboard input, 
etc. Linux does it one way, Windows does it another way, DOS does it yet 
another way, etc. In brltty, therefore, these concepts are abstracted into what 
we refer to as a screen driver.

It gets a little confusing, of course, when we refer to the screen screen 
driver. Brltty has a screen driver called screen which knows how to read 
windows maintained by the screen program. This is what's often used on 
Unix-type platforms for which brltty doesn't have a native screen driver yet.

>Is there a way to set it up so that when you hit the line down key in, say, 
>nano or man page viewer, the screen scrolls too?

Do you mean to scroll the screen rather than to move the cursor, so that, for 
example, the cursor will always stay on the middle line of the screen?
