What is the ARIA widget for nvda?

In my quest to get the radio programming software which
is stuck in "Tree View" out of the trees and doing something
useful, I was looking at the nvda keyboard shortcut list and
found:

Tabs (ARIA widget),
Tree view items (ARIA widget),
Menu items (ARIA widget) right arrow or down arrow or left arrow or up
arrow

A widget is a routine that handles certain situations and
this widget is probably not running because the programming software is
deficient in some basic design and isn't being triggered.

Anyway, my questions are:

What is the ARIA widget and is there any way to wake it up?
