Red Underlining in Document
Problem:
Why do I have red underlining in my document? How can I delete it?
Solution:
A red underline indicates that a value in a cell has been changed i.e. the cell has been "flagged as changed".
You can remove the red underline either on a global or an individual cell basis.
To remove all the flag changes at one time, from the Edit menu, select Cell Value Flags.
To remove on an individual line basis right click the particular cell, right click and select the Clear All Value Changed Flags option (for the entire file or a particular document).
