Auto-propagation or leveraging repetitive content re-uses segments that are repeated in a file. You can enable auto-propagation by selecting preferences in Preferences > General Preferences > Auto-Propagation. Refer to Auto-Propagation.
To leverage repetitive content:
On the TXLF Editor, select any translatable segment. In this example, the duplicate segments have been located with a filtered search.
Enter the translation into the first target segment.
Commit the term by using one of the following methods:
Click Next Segment or press Alt+Down
The entered target segment is saved to the TM and automatically propagates this target segment for all repeats of the source segment throughout the file.
