You can turn off Screen History, Office Tools, and productivity features for fields that contain sensitive information (like user accounts) by setting Field Security for these fields.
When Field Security is on for a field, Screen History, Office Tools, and all of the productivity features are disabled for that field. These features still work for other fields where Field Security is off. Field Security settings are saved when you save your session files.
To Turn Field Security On
In the program field you want to set, right-click and choose Field Security.
To Turn Field Security Off
