00:00:00.000 --> 00:00:08.000
You see a window and an Export button. Accessibility, often shortened to AX, describes those controls to other tools.

2
00:00:08.000 --> 00:00:16.000
That description is a tree. An app contains a window. The window contains controls, such as buttons.

3
00:00:16.000 --> 00:00:26.000
An element can expose its role: Button; its title: Export; and a supported action: Press. A tool can ask the app to press it.

4
00:00:26.000 --> 00:00:36.000
The app decides what it exposes. Some controls may be missing or incomplete. Tools need Accessibility permission to access and control other apps.
