IGCSE ICT 0417 – Document Production: Text Enhancement

17 Document Production – Text Enhancement

Learning Objective

Students will be able to apply text enhancement techniques – bold, underline, italic, superscript, subscript and case changes – using word‑processing software.

Why Text Enhancement Matters

  • Improves readability and visual hierarchy.
  • Highlights key information such as headings, definitions, formulas and references.
  • Ensures professional presentation of reports, letters and assignments.

Common Text‑Enhancement Features

  1. Bold – makes text darker and heavier.
  2. Italic – slants text to the right.
  3. Underline – draws a line beneath the text.
  4. Superscript – raises characters above the normal line (e.g., \$x^{2}\$).
  5. Subscript – lowers characters below the normal line (e.g., \$H_{2}O\$).
  6. Case changes – convert text between uppercase, lowercase and Title Case.

Applying Enhancements Using the Toolbar

In most word processors (e.g., Microsoft Word, LibreOffice Writer) the toolbar contains icons for each enhancement.

  • Select the text you wish to modify.
  • Click the appropriate icon:

    • BoldB icon.
    • ItalicI icon.
    • UnderlineU icon.
    • Superscript – icon.
    • Subscript – H₂ icon.
    • Case change – Aa or similar icon.

Keyboard Shortcuts

Using shortcuts speeds up work and is essential for the exam.

Changing Case – Step by Step

  1. Highlight the text whose case you want to change.
  2. Open the Case menu (often found under Format → Change Case).
  3. Choose one of:

    • UPPERCASE – all letters become capital.
    • lowercase – all letters become small.
    • Title Case – first letter of each word capitalised.
    • Sentence case – first letter of the first word capitalised.

  4. Confirm the change; the text updates instantly.

Practical Activity

Create a short report (150‑200 words) on a topic of your choice. Apply the following formatting:

  • Bold the main heading.
  • Italicise any foreign language terms.
  • Underline the key conclusion.
  • Insert a superscript for a footnote reference (e.g., “see note¹”).
  • Insert a subscript for a chemical formula (e.g., \$CO_{2}\$).
  • Convert the paragraph that lists the report’s objectives to UPPERCASE.

Save the document and be prepared to demonstrate the shortcuts used.

Common Mistakes to Avoid

  • Applying formatting to invisible spaces – always select visible characters.
  • Mixing superscript and subscript in the same word unintentionally.
  • Using case change on headings that already have a specific style – may disrupt heading hierarchy.
  • Relying solely on the toolbar; learn shortcuts for speed and exam efficiency.

Summary

Effective document production requires mastery of text‑enhancement tools. By using the toolbar, keyboard shortcuts, and case‑change functions, you can produce clear, professional documents that meet IGCSE standards.
