If you can see the text and are looking for where it is in your files (especially if you have multiple files) I recommend grepwin to search across all the files. It's helped tons in my groups translation of Maplestory.
Right now I'm using regular Word and it's search with my Japanese input software.
I would like to try something easier but last time I switched (From Libre Office) I lost a days full of work
because of a stupid corrupted file, so I'm afraid to try it again.
Thanks for the help tough, if you need help translating in the future let me know
