Regardless of how you’ve entered text, you can edit the properties of selected text by clicking the Properties Panel icon. If you select a text box, an element with text typed over it, or any combination of the two, the text properties section will show up in the Properties Panel.
Here, you can choose from a list of available fonts. You also can change the font size and color, make text bold, italic and/or underlined, and change the alignment of the text. You can also add hyperlinks to text (not available in the Gliffy Plugin for JIRA).
You can set different sections of text to have different properties within the same text box or element. For example, one word in a sentence can be bold and in a larger font size. All that’s needed is to select the words you want to change the properties for and make your changes.
