I'm translating a book. I would like to do it with a software that allows me to see the original one in a window and my translation in the other with an auto-scroll down. Can I do it with LibreOffice? What prominent software applications are used by the publishing industry?
I've found Translation Table for LibreOffice this is not an advanced tool but for little works is useful:
Translation Table creates a two column table, where in the first column you get the source text segmented by sentence, each sentence in a cell, and in the second column you can put your translated sentences, each one in opposite cells to the source sentences. It is not a CAT (Computer Aided Translation) tool, for such, please take a look to Anaphraseus extension or OmegaT project.
Wikipedia lists a selection of computer-assisted translation tools.
You might also try to search your favourite search engine for "translation workstation" or "translator's workstation".
