How to Fix Control Key Not Selecting Text for Annotations in Acrobat
Question details
The user is unable to use the Control key to select specific text blocks for annotations, such as strikethrough, in Adobe Acrobat.

- Product
- Adobe Acrobat XI
- Device & OS
- Windows 10
- Scenario
- Attempting to select specific lines or blocks of text to apply an annotation.
- Observed behavior
- Holding the Control key while selecting text selects multiple rows at once instead of the specific text block intended for the annotation.
Ensure that your keyboard's Control key is functioning properly outside of Acrobat, and check if the document is a scanned PDF, which might require OCR (Optical Character Recognition) before text can be precisely selected.
Restart Acrobat and Reset Preferences
Resetting Acrobat preferences can often resolve unexpected UI or selection tool behavior.
Sometimes Acrobat's internal settings become corrupted, leading to erratic behavior with modifier keys like Control or Shift. Resetting the preferences restores default tool behaviors.
Restart Adobe Acrobat and open a different PDF file. Attempt to select text while holding the Control key to rule out a document-specific issue.
Navigate to the 'Edit' menu at the top and select 'Preferences' (or press Ctrl+K on your keyboard).
Under the 'General' category on the left pane, ensure that the basic text selection tools are configured correctly and not conflicting with touch mode settings.
If the issue persists, close Acrobat. Navigate to C:\Users\[YourUsername]\AppData\Roaming\Adobe\Acrobat\[Version] in Windows Explorer. Move the 'Preferences' folder to your desktop as a backup, then restart Acrobat to force it to generate fresh preference files.

Update Adobe Acrobat to the Latest Version
Installing the latest patches ensures known bugs affecting text selection and annotation tools are resolved.
Recreate the PDF or Use Alternate Selection Methods
If the issue only occurs in one document, the underlying text structure or encoding might be corrupted.
Edit and Annotate PDFs Effortlessly with WPS Office
If Adobe Acrobat continues to give you text selection issues, try WPS Office. It includes a robust built-in PDF editor that allows you to accurately select text, apply strikethroughs, highlight, and add comments with ease. It's lightweight, free to download, and fully compatible with all standard PDF formats.
- 1. Open your PDF: Launch WPS Office and open the PDF document you wish to annotate.
- 2. Navigate to the Comment tab: Click on the 'Comment' tab at the top of the interface to reveal all annotation tools.
- 3. Select and Annotate: Use your mouse to accurately select the specific text, then click 'Strikethrough' or 'Highlight' to apply the formatting instantly.

Frequently Asked Questions
Why does my PDF select an entire paragraph instead of a single word?
This usually happens when the PDF is exported from a source document with formatting issues, or if the PDF is actually a scanned image with a poorly aligned, invisible OCR (Optical Character Recognition) text overlay.
How can I force text selection in a stubborn PDF document?
Try using the standard Select Tool without any modifier keys. If that fails, 'flattening' the file by printing it to a new PDF using a virtual PDF printer often restructures the text so it can be selected normally.
Will updating Adobe Acrobat fix text selection bugs?
Yes, installing the latest patches for your version of Acrobat often resolves known bugs related to the graphical interface, unexpected modifier key behaviors, and text selection errors.
