Question details
The user needs to restore the default behavior of the Up and Down arrow keys in Word so that they move the cursor one line at a time instead of moving by paragraph or requiring the Ctrl key.

- Product
- Word
- Device & OS
- not provided
- Scenario
- Navigating through a Word document line-by-line using keyboard arrow keys.
- Observed behavior
- The Up and Down arrow keys are behaving differently than expected, possibly jumping by paragraph as if the Ctrl key is pressed, due to customized shortcut settings.
Before modifying Word settings, test your arrow keys in another application like Notepad to ensure there is no hardware issue or stuck 'Ctrl' key on your keyboard.
Restore Default Keyboard Shortcuts for Arrow Keys
Use the Customize Keyboard dialog in Word to remove conflicting custom shortcuts and restore standard line-by-line navigation.
In Microsoft Word, standard keyboard navigation can be altered by user customization or add-ins. Resetting your key assignments ensures the arrow keys function normally without requiring the Ctrl modifier.
Launch Microsoft Word, click on the 'File' tab in the top-left corner, and select 'Options' from the bottom of the menu.
In the Word Options dialog box, select 'Customize Ribbon' from the left-hand pane. Next to the 'Keyboard shortcuts' label at the bottom, click the 'Customize' button.
In the Customize Keyboard dialog, you can manually locate the 'LineUp' and 'LineDown' commands to check their current bindings. To quickly fix the issue, click the 'Reset All' button to restore all default shortcuts, removing any conflicting assignments.
Click 'Close' and then 'OK' to save your changes. Return to your document and press the Up and Down arrow keys to verify they now move the cursor one line at a time.

Frequently Asked Questions
What is the default function of Ctrl + Up/Down arrow keys in Word?
By default, holding the Ctrl key and pressing the Up or Down arrow keys moves your text cursor to the beginning of the previous or next paragraph, respectively. It is designed for faster navigation through large blocks of text.
Why does pressing the down arrow scroll the page instead of moving the cursor?
This behavior occurs when the Scroll Lock feature is turned on. To fix it, locate the 'Scroll Lock' or 'ScrLk' key on your keyboard and press it once to disable the function. Your arrow keys should then return to moving the cursor.
Can an add-in cause my arrow keys to malfunction in Word?
Yes, third-party add-ins or macros can override default Word keyboard shortcuts. If resetting the shortcuts in the Customize Keyboard menu does not work, try launching Word in Safe Mode to see if an add-in is causing the interference.
