dsh-esc-stop

You have launched a long generation in DeepSeek Harness Web, the output is clearly heading the wrong way, and now you have to shift your eyes to find the Stop button. dsh-esc-stop eliminates that extra step: as long as the conversation input holds focus, a single Esc press cancels the current turn instantly, no mouse required.

Under the hood the plugin calls the Harness conversation.cancel() API, the exact same path the native stop button uses, so queue semantics, error surfacing, and session state all stay consistent. The trigger is deliberately conservative: only an unmodified Esc pressed inside the main conversation input is honoured. Combinations with Ctrl, Alt, or Shift, key auto-repeat, idle sessions, one-shot sub-agents, and any UI component that has already consumed the Esc event (pop-ups, command palettes, settings panels) are all ignored, so you will not accidentally cancel a run while pressing Esc in another field.

It is aimed at keyboard-first users who iterate prompts frequently, babysit sub-agent output, or produce long-form text in Harness Web many times per session. After installing and refreshing the page, cancelling a turn goes from one click to one keystroke, with no workflow changes, no external services touched, and no configuration to worry about.
