Numbers, variables, and operators appear in different colors, and phrases Soulver understands are underlined. ### Line highlighting You can highlight the body of a line, its label, or its comment separately. Highlighting replaces the syntax coloring for that part of the line. **On Mac:** Place the cursor in the body, label, or comment you want to highlight, then choose a color from **Format > Highlight**. You can also control-click that part of the line and choose a highlight color from the contextual menu. **On iPad & iPhone:** Select text in the body, label, or comment, then choose **Highlight** from the editing menu and select a color. ### Customizing highlighting colors Customize the colors Soulver used to indicate the various parts of your expression in the **Styling** settings pane:
