When working on a document in stages, it can be helpful to save and close the file, then reopen it.
To save a file from the TXLF Editor File tab:
Save (or press Ctrl+Alt+S) to save the active file to PD manually.
Save File As Translated (or press Ctrl+Alt+S) to save the active file in its translated state to a local drive.
A progress bar appears. Upon completion, the file is in Project Director.
