The Highlight and Select Text tools select text you don’t want to select.
Why is this Happening?
Text in a PDF is stored in individual lines instead of blocks or paragraphs. As a result, dragging the cursor downward to select multiple lines of text might select text on the other side of the page.
Here are a couple alternative methods you can use to accurately select and highlight text. Each is a little different and may be helpful in different circumstances.
Using the Select Text tool and the Context Menu
Holding down the Ctrl key while using the Select Text tool releases its snap-to-text function, allowing you to draw a rectangle around the text you want to select.
- Go to Edit > Select > Select Text (Shift+T) or click the Select Text button in the Navigation Bar.
- Hold down the Ctrl key, then click and drag to draw a rectangle around the text. The selected text will have a temporary blue highlight.
- Right-click on the selection text and click Highlight Selected Text.
Using a Freehand Highlight
You can manually activate the Highlight tool’s pen mode by holding down the Ctrl key. This disables the snap-to-text function, allowing you to draw a freehand markup.
- Click Markup > Pen > Highlight (H).
- Hold down the Ctrl key and draw a line over the text you want to highlight. Draw a straight line by holding down the Ctrl and Shift keys.
