Questions

Can ChatGPT control Syntax Highlight?
On a Mac with BCD, yes, through the app's window: ChatGPT can open Syntax Highlight, read the buttons and text it shows, press buttons, type and pick menu items. How far that goes depends on how much of its window Syntax Highlight exposes to macOS accessibility.

Does this work on Windows?
No. BCD controls app windows only on a Mac. On Windows and Linux it works with files and commands.

Is it safe?
A new computer starts read-only. Controlling the screen and apps is turned on per computer, and macOS asks once before BCD may control apps.
