When in Illustrator, you will see a question mark icon on each Astute Graphics panel. When you click on this, then providing your Astute Manager is running, it will open the related training material directly in the Astute Manager, giving text and example images of the functioning of each button, option, control and menu.
If you don't see this, please check the following:
What is your account status? - This feature will only function for an active account, a trial account or if using a free plugin.
What version of Astute Manager are you using? - This feature was introduced in Astute Manager v3.8, please ensure you have the latest version.
Is your Astute Manager app running? - the app does not need to be open, but you should be logged in to it and the menu bar icon (macOS) or task tray (Windows) should be active.
