Text Markup: Highlight, Underline, Strikethrough, Squiggly

Text markup annotations decorate existing selectable text on the page. They require either a native-text PDF or an OCR'd page — see 06.1 if the page is image-only.

The Four Markup Tools

Workflow

1. Activate the tool (toolbar or Tools menu).
2. Click and drag across the text you want to mark.
3. Release. The markup snaps to the text bounds (it knows where characters are).
4. The tool stays active — drag again to mark another passage.

Multi-Line Markup

Dragging across several lines marks each line as a separate "quad" in the PDF. The markup renders as one visual object but is actually a set of rectangles matching the text layout.

On Non-Text PDFs

If you drag on a page with no OCR text:

• A message in the status bar says No text found at this position.
• No markup is created.

Fix: run OCR (Tools → OCR → OCR This Page) first. See 06.1.

Color and Opacity

• Pick a color in Tool Options before drawing, or
• Select an existing markup and right-click → Change Color (six presets + Custom).

Highlight opacity defaults to ~30% so the text stays readable. You can adjust via the context menu.

Selecting a Markup

Click anywhere on the highlighted text. The markup is shown with a dashed outline. Note:

• Text markup does NOT show resize / rotate handles — its shape is dictated by the text it covers.
• You can still change color, opacity, delete, and group.
