Final answer:
In InDesign, the ">>" (double chevron) symbol indicates overset text, suggesting that not all the text fits within the frame. To resolve this, you can adjust the text frame, link it to another frame, or edit the text. Edits are highlighted in red text, with additions in plain red and deletions in red with a strikethrough.
Step-by-step explanation:
In InDesign, the double chevron symbol (">>") is often used to indicate that there is more text than can be displayed in the text frame. This condition is known as overset text, where text doesn't fit within the existing frame boundaries and so is hidden from view. You will generally see this symbol appear at the end of a text box when there is additional text that can't be displayed. If you see this symbol, you can address it by resizing the text frame to accommodate the extra text, linking the text frame to another text frame to allow the text to flow, or editing the content to reduce its length.
When text edits are made, such as additions or deletions, InDesign highlights these changes for easy identification. Added text is typically displayed in red, while deleted text may appear in red with a strikethrough. Furthermore, in electronic versions of a document, changes are often accompanied by a red square that serves as a hyperlink to an entry detailing the edit, with the associated page number also hyperlinked for easy navigation.
