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:

  1. Go to View > Invisibles.

  2. 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).

  3. Delete the Indent Here marker.
