 ### الخيارات
 
+- `theme` - يحدد سمة واجهة المستخدم. [تعرف على المزيد](/docs/themes).
+- `keybinds` - يخصص اختصارات لوحة المفاتيح. [تعرف على المزيد](/docs/keybinds).
 - `scroll_acceleration` - فعّل تسارع التمرير على نمط macOS لتمرير سلس وطبيعي. عند تفعيله، تزداد سرعة التمرير مع إيماءات التمرير السريعة وتبقى دقيقة للحركات الأبطأ. **يتقدّم هذا الإعداد على `scroll_speed` ويستبدله عند تفعيله.**
 - `scroll_speed` - يتحكم في سرعة تمرير واجهة TUI عند استخدام أوامر التمرير (الحد الأدنى: `1`). القيمة الافتراضية هي `3`. **ملاحظة: يتم تجاهل هذا إذا تم ضبط `scroll_acceleration.enabled` على `true`.**
 - `diff_style` - يتحكم في عرض الفروقات (diff). القيمة `"auto"` تتكيف مع عرض terminal، و`"stacked"` تعرض عمودًا واحدًا دائمًا.
+- `sidebar_position` - يتحكم في موضع الشريط الجانبي. `"right"` (الافتراضي) يبقيه على اليمين، `"left"` ينقله إلى اليسار.
 
 استخدم `OPENCODE_TUI_CONFIG` لتحميل مسار إعدادات TUI مخصص.
