Quick Copy‑Editing Tips
Always use sentence case for body text.
Use title case for headings that are 5+ words long, but sentence case is also acceptable in modern web writing.
Avoid ALL CAPS for long paragraphs – it reduces readability.
After pasting text from a PDF or Word document, use “Normalize with Single Space” to clean up strange spacing.
