Short Answer 
Text features enhance understanding by providing supplemental information, organizing content, and reinforcing key ideas. They include items like sidebars and headings that add context and structure, making navigation and comprehension easier for readers. Visual elements also play a role in emphasizing important arguments and themes within the text.
Step 1: Offering Supplemental Information
Text features enhance a reader’s understanding by providing supplemental information that elaborates on the main content. This information can include items such as sidebars, captions, or footnotes that add additional context. By integrating these features, the reader gains a broader perspective, which helps in grasping the core message of the text.
Step 2: Providing Organization
Structure is crucial in effective communication. Text features play a key role in organizing the content in a logical manner. This can involve the use of headings, bullet points, and numbered lists which simplify navigation throughout the text, making it easier for readers to find specific information or follow the flow of ideas without getting lost.
Step 3: Reinforcing Ideas
Reinforcing the main arguments is an important aspect of effective writing. Text features help in supporting and reinforcing ideas discussed in the main body of the text. This is achieved through visual elements like graphs, charts, or highlighted quotes that emphasize key points and remind the reader of the main themes and arguments presented.
