Click on the View File Icon 
After selecting the File you wish to work on, click on the Manuscript icon 
In the Project File Editor, you will see all the segments available for editing in the file.
Project File Editor:
Editing View
You can edit a file using either the default view shown above, or Focus Mode, which changes the view to full screen. Click Toggle Focus Mode to switch between the two views.
Segments can be filtered based on their status. The filter allows you to view available segments, segments left to edit, unavailable segments and segments with errors.
Note: Segments edited by other Editors will automatically become unavailable to you.
Editing a File
To open the first available segment, click on any available segment or use the Start button.
You can scroll through all of the available segments and use the Focus button to quickly return to the segment you are editing.
Using the search bar will allow you to look up a string and replace it.
Once you have made your edits, click Save to move to the next available segment. You can also skip a segment and return to it later or leave it for another Editor.
After you have finished editing, click Submit File. This will open up the batch validation window to perform one last error check. Once completed, you can confirm the file.
Locking a File
By selecting Lock File you can assign the Project file to your account and become the only Editor allowed to edit it. This will make the file unavailable to other users. Files will automatically become locked once you save a segment.
Keep in mind this will also make you unable to access other files until this file is completed.
You can manually remove the file lock by selecting Unlock File or using the Release File icon 
Export Project Segments
Use the Save to Excel button to download an export of the segments you have worked on.
