+3. **Customizing for Language-Specific Keyboards**:
+
+   - If your keyboard is in a language other than English, such as German, you may need to adjust the hotkeys. For example:
+     - Original hotkey: ``` alt+` ```
+     - Adjusted hotkey: `alt+|` or `alt+vk_oem_5`
+
+4. **Test Your Hotkey Setup**: After configuring, test the hotkeys to ensure they perform the intended actions across different keyboard layouts.
+
+By following these steps, you can adapt hotkeys for various non-English keyboard layouts, ensuring smooth functionality regardless of the language or region of your keyboard.
