We've never been able to change the nav wiki-wide (with the minor exception to basic color via the Special:ThemeDesigner). The text used to be able to be changed via MediaWiki:Tooltip-search, not CSS. I've asked about this twice (with the original global version and the updated one), but there still has been no acknowledgement either way.
