Word adding another row

I have checked some, but haven´t found what I´m looking for.
I´m guessing it´s simple, but I can´t find it.

I want to be able to change row in a word document.
When writing text i use
word_document_main.Range.InsertAfter("Text")
where word_document_main is defined as Word.Document

What is the command to add another line to the row beneth.
Ex.
Text
Text1

Thanks for answers
