Follow the steps below to apply bold, italic, underline & strike (i.e. Font styling).
1. Click on the text frame and highlight the text within that frame that you'd like to style.
Notice: Font styling can be added to individual characters within a single text frame. That means you can have a single word with multiple styling in it.
2. In the left panel, click on any of the options in the style control. Once selected, you can click again to remove it.
Notice: Bold & Italic are not always present with every font type, but underline & strike are always available. This is due to the creator of the font not producing the bold & italic versions.
