:In some cases, it can be very helpful to copy the source segment into the translation box, e.g. when the source segment contains many numbers, or when it contains special terminology which does not require much translation work.
For these cases, there are two helpful commands:
·
Copy source text :
This command copies the text of the source segment into the translation box (if the translation box is empty).
·
Copy source text in next translation unit 
:
This command is, in fact, a combination of two other commands: Open next translation unit and Copy source text. This command can be helpful when you know for sure that it makes sense to copy the source text into the next TU.
How special document elements are treated through these functions will be explained in the next section.
