Thread:Support/About Special:AdvancedTranslate

This page lists various pagenames for special pages which are probably used in the url too. These names are made of several words which are separated by starting the new word with an uppercase character. However, hindi does not have differentiation of case. So how do I differentiate the words? Do I use - or _ or. or something else, or is space allowed (that would be best)?

PS:Are these pushed to the WMF projects along with the rest of the updates, or are they pushed later? And what effect will updating have? Will the older wikilinks, magic words etc keep working?
