It is very seldom that I need to do this, so it is OK to be able to do it without an add-on. Also, the same trick works 'elsewhere'. In fact, I 'discovered' it working on a wordpress site where one title had a very long 'technical term' in the title.
By the way: the automatic hyphenation for norwegian (language) is just getting worse and worse in all apps. More and more words are hyphenated 'as they were english', for example: words ending on ning or ding that used to (correctly) hypenate before the n or d is now hyphenating before the i.
