Fix Excel Right Alt + Equals Shortcut Typing X Instead of SUM
Question details
The user needs to fix an issue where pressing the Right Alt + = shortcut types the letter 'X' instead of triggering the SUM function.
- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Attempting to quickly sum a column or row of data using the standard AutoSum keyboard shortcut.
- Observed behavior
- The Right Alt + = shortcut fails to insert the intended SUM formula and outputs an 'X' instead, whereas the Left Alt + = combination works perfectly.
Check if your current Windows keyboard layout utilizes the Right Alt key as an 'AltGr' (Alternate Graphic) key, which overrides standard shortcuts to type special characters.
Verify and Change Windows Keyboard Layout
Switching to a standard US QWERTY keyboard layout prevents the Right Alt key from acting as an AltGr key.
In many international keyboard layouts (such as US-International or UK), the Right Alt key is mapped as AltGr. When AltGr is combined with the Equals key, it can produce alternative characters like 'X' instead of sending the shortcut command to Excel.
Press the Windows key + I to open Settings, then navigate to Time & Language > Language & Region.
Look under your preferred languages. If you are using an 'International' layout, click the three dots next to the language and select Language options.
Click 'Add a keyboard' and select a standard layout like 'US (QWERTY)'. Remove the international layout if it is not needed.
Press Windows + Spacebar to quickly cycle between your installed keyboard layouts until the standard layout is active, then test the shortcut in Excel.
Identify Conflicting Background Software
Close background utilities that might be intercepting the Right Alt key combination.
Use Standard AutoSum Alternatives
Utilize built-in Excel alternatives to quickly sum your data without relying on the Right Alt key.

Frequently Asked Questions
Why does Left Alt work for AutoSum but Right Alt doesn't?
On many regional and international keyboard layouts, the Right Alt key functions as an 'AltGr' (Alternate Graphic) key. Windows treats AltGr differently than the Left Alt key, prioritizing it for typing special characters rather than executing application shortcuts.
Can I remap my Right Alt key to act like a normal Alt key?
Yes. You can use utility software like Microsoft PowerToys (specifically the Keyboard Manager feature) or third-party apps like SharpKeys to remap the Right Alt key so it functions identically to the Left Alt key.
Can I customize the AutoSum shortcut inside Excel?
Microsoft Excel does not offer a native menu to customize default keyboard shortcuts. If you want a different shortcut for AutoSum, you would need to record a macro for the SUM function and assign a custom keyboard shortcut to that specific macro.
