This is a defect in QuarkCopyDesk 7.4. You should be able to Undo any formatting command you enter for text.
To remove the Indent Here marker, follow these steps:
- Go to View > Invisibles.
- Find the location in the text where you applied the Indent Here keystroke (it displays a thin, dotted, vertical line placed immediately to the left of the following character).
- Delete the Indent Here marker.
