Sanity Check of Prefix Components
Prefix components in QuickSilver files must always be positioned at the beginning of a paragraph – otherwise crashes may occur when opening the document with QuickSilver, or the document may be displayed incorrectly. For this reason, a sanity check makes sure that the prefix components are located at the beginning of a paragraph.
If this is not the case, an error message is displayed:
The editing state of the paragraph cannot be changed until the prefix component is repositioned.
