Auto Analysis Settings Panel

Selecting View > Auto Analysis Settings displays a panel allowing you to select the following options:

Non-modal analysis progress display. If this is checked, it performs an analysis without displaying a modal dialog so that the IDE remains active whilst analysis is under way. Analysis progress is displayed in the Analysis details window. The window is automatically hidden during modal analysis.
Analyze after saving a file. If this is checked, it triggers an analysis when a file that is part of the active QAC project is saved. All modified files are saved and analysis triggered for just the updated files. Analysis can be either modal or non-modal.
Save and analyze after inactivity. If this is checked, it triggers an analysis (modal or non-modal) after the specified period of inactivity.
Perform a quick analysis when automatic re-analysis may be slow. If this is checked it, it performs a faster analysis when full analysis could be slow.
