After translating segments, the translation memory should be updated with the translation. The Commit All option updates all target segments and the Commit option updates the current target segment to the TM.
To update the translation memory on the TXLF Editor:
On the Translation tab, click Commit All in the Translation Memory group or Commit in the Segment group.
The translation memory is updated for the entire file or the current segment. When a modified segment is committed to the TM, the highlight color changes to purple.
