# Set font type and size

1. Select the shape by `name` you want to modify. See [here](https://docs.powerpointgeneratorapi.com/knowledge-base/finding-shape-names) to find shape names.
2. Specify the text need amending under `text_run`. Text within one textbox can be split into multiple chunks.  
3. Add font setting `font_type` or font size setting `font_size` for selected text under `text_properties`.
4. Insert `new_line` as boolean before another `text_run`.
