Ctrl+A followed by F9 updates all field codes in the text layer of the document.
I hope you kept a backup.


When something like this happens, Ctrl+Z (undo) is your friend.

Thanks for answer, but when the command Ctrl+A+F9 is performed, one wouldn´t expect the total marking of the entire document to remain afterwards. How do you remove that marking, so you can get on with your work? Ctrl+Z would - I presume - take the fieldcodes back to where they were before updating, right?
And how does the deleting of the entire text occur - since I didn´t press any delete-key?

And yes - I did have a backup
