This is jwShiftSpaceKey, famous for its Shift+Space Korean-English switching feature.
It appears development ceased around late 2024 when the creator’s blog disappeared.

You can safely download jwShiftSpaceKey from this post.
Though it’s regrettable development has stopped, I hope this still helps those seeking jwShiftSpaceKey.

It works well on Windows 10 and Windows 11.

What is jwShiftSpaceKey?

jwShiftSpaceKey is a free utility that enables switching between Korean and English input using the Shift + Space key combination on Windows.
Developed by badayak.com, it’s a simple yet useful program that gained popularity.

For those who have used Shift + Space for Korean-English switching since the Hangul Word Processor era, this key combination is second nature.
Since the location of the Korean-English key varies by keyboard or is sometimes absent altogether, many users find the Shift + Space combination more convenient.

This utility is especially essential for keyboards like the Happy Hacking Keyboard (HHKB) or 60% keyboards that lack a dedicated Hangul/English key.
Additionally, many Mac users frequently access Windows via RDP.
Some users unify their Korean-English switching across both Mac and Windows by using Shift + Space.

Windows 11/10 Compatibility

It works normally on Windows 11.
However, starting with Windows 11 22H2, a new IME has been implemented, which may cause issues in some environments.
On Windows 10, it works without problems in most environments.

If you encounter issues:

  • Windows Settings → Time & Language → Language & Region
  • Korean options → Use an older version of Microsoft IME

Since jwShiftSpaceKey is no longer under active development, it’s helpful to know about alternative programs.
