Type Tool Feature or Bug?
OK this is weird, and I discovered it by accident so I don't know if it is a bug or a strange documented feature.
Lay down some text using Miriad Variable Concept —I have tried it with a couple of the variable options and it did the same thing.
Now double click the type layer to highlight the text, and start typing over the text.
At some point throw in a forward slash, and keep typing.
The rest of the line suddenly grows serifs, least ways it does for me.
What The Heck? I tried some non variable fonts and it didn't happen. I have not tried it with the other variable fonts as of yet.
