Screen history and keystroke productivity features (Spell Check, Recent Typing, Auto Complete, and Auto Expand) are automatically disabled while a macro is running. (Running macros with these features enabled can significantly impact performance.)
This property is always set to true when a macro starts. Setting this property to false enables these features while a macro is runnning.
To disable productivity for an entire session, use the properties on the Productivity object or set these optons in the user interface (in the Configure Productivity Defaults settings dialog box).
