Original Pull Request: https://github.com/anomalyco/opencode/pull/13375

State: open
Merged: No

Fixes #13368

Problem

On Windows, CTRL+BACKSPACE does not delete the preceding word in the TUI input field. This is because Windows Terminal doesn't properly set the ctrl modifier for backspace keypresses. ALT+BACKSPACE works as a workaround.

Solution

Add a platform-specific workaround that uses the Win32 GetAsyncKeyState API to check if CTRL is actually held when backspace is pressed, bypassing the terminal's incorrect modifier state.

Changes

  • Add win32IsCtrlHeld() function in win32.ts using user32.dll's GetAsyncKeyState
  • Handle CTRL+BACKSPACE in prompt input handler when on Windows and CTRL is detected via API
