Font tokens/variables

I i understand you request correctly, you wish to have the ability to create a dynamic font style for the Font-family, Font-weight and Font-size.
all these are possible by adding “sting” type variables to your local variables. here is an example:

Then you bind them to your typography styles, like this example:

Then you can also save this text as a style and change it later.

Tip: you must write the font name exactly as it is shown in the fonts menu (capitalization and everything)

Hope this helps!
