user → user ✓   (not "úẻ")
push → push ✓   (not "púh")
Press ESC after typing to manually restore any word: user → úẻ → ESC → user

​
Smart Per-App Mode

Gõ Nhanh remembers your ON/OFF preference for each application:
  • Code in VS Code (OFF) → Switch to Slack (ON) → Back to VS Code (OFF)
  • No manual toggling needed

Automatic Input Source Following

Using multiple input sources? Gõ Nhanh automatically disables when you switch to:
  • Japanese (あ)
