I'm sure I'm beating a dead horse, alas...I'm stuck:

I want to have a 2 column document - one side original language text, on the other a translation. The document is some pages long. I want to copy my original text in full one the left column and then , line by line add translation to the right side without having text from the left column move.

I'm sure it's dead simple, but it totally escapes me.

Help appreciated !
