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?
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".
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.
