Nice find.. Good self service

The exact phrase you need is this:

Translation = Text you want.

I’ll add two tips:

1. you should also be able to do this via the front end phrasing tool
    
2. changing the phrase changes it site-wide for all events, but you have options if you need it to be unique for specific events
   1. Events that link out to external registration pages give you the option to customize the text for the registration button
   2. I believe @leo-inspired ‘s reply to my question here indicates you could put custom CSS to style specific pages, so perhaps you could do that to style individual reg buttons on events that use the native registration feature
