When a segment is repeated in a document, it is called a repetition. A repetition can be easily identified in Memsource Editor, as blue arrows are displayed next to the repeated segment.
Once a user confirms a repeated segment, all the repeated instances of that segment below it will be updated with the confirmed translation. Please note that repetitions are only propagated downwards.
Sometimes it is necessary to introduce a "repetition exception," which allows a repeated segment to have a different translation than all the other repeated segments. This can be done by clicking on the repetition icon, which will become crossed. This will ensure that a translation for such a segment will not change in line with the other repetitions.
