Gettext / poedit - same string on many files?

Let’s say you have the string “home” into 5 files. Would you go and translate this in every file?

How to handle this? Any easy way to “group” them? Or does poedit does this automatically?

I am about to translate a big site. Gettext has great benefits (fastest method, better collaborative methodology, cleaner code etc.) over constants.

thank you!
