The Quick Assist support improves the development work flow, offering fast access to the most commonly used actions when you edit XML Schema documents.
The Quick Assist feature is activated automatically when the cursor is positioned over the name of a component. It is accessible via a yellow bulb help marker placed on the cursor line, in the line number stripe on the left side of the editor. Also, you can invoke the quick assist menu by using the Alt + 1 keys (Meta + Alt + 1 on Mac OS X) keyboard shortcuts.
