Auto-Propagation

Auto-Propagation is a feature of Lilt Translate that saves linguists time by automatically completing and confirming repeated segments. Auto-propagation affects only the current document.

Enabling the auto-propagation functionality

By default, forward and backward auto-propagation are both enabled. You can enable or disable auto-propagation for confirmed segments through the Settings tab by selecting/deselecting the following options:

  • Forward Auto-Propagation: Propagates changes to all segments going forward, e.g. all later repetitions. When a segment is confirmed, Auto-Propagation copies the confirmed target text to all forward repetitions (including previously confirmed segments) in the document and marks those segments as confirmed. 
  • Backward Auto-Propagation: Propagates changes to all segments going backward, e.g. all previous repititions. When a segment is confirmed, Auto-Propagation copies the confirmed target text to all backward repetitions (including previously confirmed segments) in the document and marks those segments as confirmed. 

Use cases for Forward and Backward Auto-Propagation

  • Forward and Backward Auto-Propagation are both enabled by default. This is a useful way to make sure translations are consistent across a document, because if you make a change to a segment, all segments with matching source text will update their target text to match.
  • If you want to ensure you do not overwrite content in confirmed segments, turn off both Forward and Backward Auto-Propagation.
  • Enabling only Forward Auto-Propagation is a good way to speed up translation (by automatically populating segments you haven't reached yet), while making sure to not overwrite content in matching segments you have already processed.
  • It is not common to only enable Backward Auto-Propagation.

Note that in Review mode, with Forward or Backward Auto-Propagation enabled, changes to accepted segments will overwrite segments that are not part of the review sample.
