01.The Mystery of Swapped Keys
In 2026, with the popularity of imported mechanical keyboards, it's very common to buy a keyboard with the American layout (ANSI) and try to use it with Brazilian settings (ABNT2). This causes symbols to not match what is printed on the key. Solving this in Windows 11 takes less than a minute, provided you know exactly which layout your hardware has.
Don't do it Manually.

02.1. Identifying Your Layout
Before configuring, look at your keyboard:
- ABNT2: Has the 'Ç' key and the 'Enter' key is L-shaped (large). The '@' symbol is usually on the '2' key.
- US (International): Does not have the 'Ç' key. The 'Enter' key is a small horizontal bar. The '@' is on the '2' key, but accents work differently (e.g., press ' and then 'c' to create 'ç').
03.2. How to Configure in Windows 11
Step-by-Step:
1. Go to Settings > Time & Language > Language & Region.
2. Under 'Portuguese (Brazil)', click the three dots (...) and select Language options.
3. Scroll to 'Keyboards' and click 'Add a keyboard'.
4. Choose 'Portuguese (Brazil ABNT2)' or 'United States (International)'.
5. Tip: Remove keyboards you don't use to prevent Windows from switching automatically during use.
04.3. The Magic Shortcut
If your keyboard layout changes "out of nowhere" while gaming or typing:
Attention: The shortcut Windows + Space toggles between installed layouts. In 2026, many users press this accidentally. If your keyboard acts up, try this shortcut to return to the correct layout immediately.
05.4. Special Character Mapping
🔤 Character Combination Sequences
On US International layouts, creating accented characters follows specific rules:
| Character | ANSI (US) Combo | ABNT2 (BR) Combo | Description |
|---|---|---|---|
| ç | ' + c | Single key (Ç) | Cedilla directly |
| á | ' + a | ' + a | Acute accent |
| ã | ~ + a | ~ + a | Tilde |
A1.12. Technical Architecture & Troubleshooting
🔧 Scancode Mapping Breakdown
Every keypress travels through multiple stages before appearing on screen:
| Stage | Component | Output |
|---|---|---|
| 1. Hardware | Keyboard Matrix | Physical Scancode |
| 2. System | Input Method Manager | Virtual Key Code |
| 3. Application | User Interface | Glyph Rendering |
💡 Pro Troubleshooting: Input Reset
If settings are correct but input is still wrong, restart the service with PowerShell:
powershell.exe -Command "Restart-Service -Name 'TabletInputService'" (This also handles modern touch/keyboard inputs).
