Find/Replace in Storyline 3

Hi there,

I try to replace a font and there is a description to do that:

https://community.articulate.com/series/storyline-3/articles/articulate-storyline-3-user-guide-how-to-replace-fonts?_ga=2.230972959.1012002610.1568026595-852821201.1566204500

but in my storyline 3 version, I can't find this Find/Replace, neither on home tab nor on other tabs. And with Strg+F, I can only find and replace a specific text but not a font.

Update 6: 3.6.18134.0

Can you explain my fault please?

Thanks

Holger Scheer
