- Product
- Excel
- Device & OS
- not provided
- Scenario
- Editing data inside a cell and attempting to add a manual line break using the Alt+Enter keyboard shortcut.
- Observed behavior
- The Alt+Enter shortcut successfully creates a line break with one Alt key (e.g., Left Alt) but fails to register when using the opposite Alt key (e.g., Right Alt).
Ensure you are actively editing the cell contents by double-clicking the cell or pressing F2 before attempting to use the Alt+Enter shortcut.
Test Keyboard Hardware and System Layout Settings
Determine if the issue is a physical hardware defect with the specific Alt key or a system-wide mapping problem.
Often, the Right Alt key acts as an 'AltGr' key on international keyboards, meaning it won't execute standard Alt commands. Verifying the hardware behavior outside of Excel is the best first step.
Open Notepad or Microsoft Word, press and hold the problematic Alt key, and press Enter to see if it functions correctly outside of Excel.
Connect a different keyboard to your computer via USB or Bluetooth to rule out physical damage or debris under the specific Alt key.
Go to Windows Settings > Time & Language > Language. Check your active keyboard layout to ensure it matches your physical keyboard (e.g., US English instead of International).
Restart Excel in Safe Mode and Disable Add-ins
Determine if third-party Excel add-ins are interfering with the keyboard shortcut functionality.
Check Accessibility Settings and Background Software
Disable third-party software or accessibility features that might be remapping your keyboard shortcuts.

Frequently Asked Questions
Why does Right Alt+Enter fail but Left Alt+Enter works in Excel?
In many international keyboard layouts (such as UK or Spanish), the Right Alt key functions as the 'AltGr' key to type special characters. Because it sends a different signal to the operating system, it does not trigger the standard Alt modifier command required for the line break shortcut.
How do I force a line break in a cell without using the keyboard shortcut?
You can use the 'Wrap Text' feature on the Home tab to automatically break lines based on the column width. Alternatively, you can use an Excel formula like `=A1 & CHAR(10) & B1` while having 'Wrap Text' enabled to insert line breaks dynamically.
Can background gaming software disable my Alt key in Office apps?
Yes, gaming software like Razer Synapse, Logitech G HUB, or Corsair iCUE often feature a 'Game Mode' that disables specific keys or remaps the Alt key to prevent accidental presses during gameplay. Disabling this mode usually restores normal shortcut functionality in Excel.
