Hangul Block Splitter

Hangul Block Splitter is an NVDA add-on that breaks Hangul syllable blocks into Jamo and lets you read, describe, or copy the split result quickly.

Features

• Splits selected Hangul text first.
• If nothing is selected, uses your configured default scope: single block under cursor, current word, or current line.
• Accepts and processes only Hangul script characters; non-Hangul input is ignored.
• Supports optional complex-letter splitting (ㅘ -> ㅗㅏ, ㄳ -> ㄱㅅ).
• Supports optional spacing between split letters.
• Includes a splitter dialog with editable input and read-only output.
• Lets you close the splitter dialog with Escape.
• Adds a Tools menu item so you can open the splitter without a gesture.
• Exposes all commands in Input Gestures so you can rebind them freely.

Default gestures

• NVDA+alt+h: Describe characters of split selected Hangul text (or the configured default scope under cursor). Press twice to copy the split result to clipboard.
• NVDA+ctrl+h: Cycle default split scope when no text is selected (single block / word / line).
• NVDA+shift+h: Open the splitter dialog.

Rebinding gestures

Go to NVDA menu -> Preferences -> Input Gestures, then find the Hangul Block Splitter category.

You can also bind commands that have no default gesture:

• Copy split result to clipboard
• Toggle complex-letter splitting
• Toggle insertion of spaces
• Toggle live update in dialog
