dsh-enter-combination

中文说明

Pick which key sends a message and which key breaks the line in the DeepSeek Harness composer. Enter sends and ⌘/Ctrl+Enter breaks the line out of the box; either one can be re-recorded.

Settings

设置 → 发送按键 (one section of its own in the settings drawer).

Row	Default	What the key does in the composer
发送	Enter	sends the draft to the AI
换行	⌘Enter on macOS, Ctrl+Enter elsewhere	moves the caret to the next line, without sending

Click a key button and press the combination you want: the next real key is recorded together with the modifiers held at that moment, and the row shows it right away. Esc cancels, clicking the button again cancels too, and a chord the other row already owns is refused with a one-line hint instead of silently shadowing it.

How it hooks the composer

Both chords are shipped internal wiring — the composer's own keymap turns Enter into a submit and Shift+Enter into a line break, and neither is exposed as a slot. So this plugin listens for keydown on document in the capture phase, before the composer sees it, and then replays the shipped path:

• send → the session's public submit action (conversation.input.for(scope).actions.submit()), the same transaction the Send button runs. Two guards: a held key does not queue a burst of sends, and a composer with no session behind it is left alone so its own Enter still works.
• newline → re-dispatches a Shift+Enter keydown on the composer's contenteditable, which is exactly the chord the editor already treats as a line break. The replay is untrusted, so the listener ignores it.

A composing IME keeps its Enter: while the input method is composing, both chords are left to the composer.

Storage

localStorage['dsh-enter-combination'], per browser profile. There is no host half to persist: only this page's composer reads the mapping, and the mapping is two chords. The cost is that the same profile opened on another machine starts from the defaults again.

Install

Needs a DeepSeek Harness build that loads plugin bundles (dsh.bundle in package.json).

dsh plugin --profile desktop add link:/absolute/path/to/dsh-enter-combination

That links the folder into the active profile (link: in the profile package.json) and adds the bundle to dsh.profile.bundles, so the profile tracks this source tree instead of a copy.

client.js is re-read on every page load, but the plugin itself only mounts when Harness boots: restart Harness (quit and reopen the app) to see the section for the first time. Later edits to client.js only need a page refresh.

Test

npm test

test/self-check.mjs loads client.js the way the module loader does, stubs the DOM, and asserts the interception (defaults, the shift-enter replay, unrelated inputs, IME, held key, no session) and the recorder (recording a chord, cancelling with Esc, refusing the chord the other row owns, unusable storage falling back to the defaults).

Limits

• The chords are matched on event.code plus the four modifier flags, so they follow the physical key rather than the layout's character: ⌘Enter stays ⌘Enter on a Dvorak layout, and two keys that produce the same character are still two different chords.
• Characters that come from the layout (e.g. ⌘↩ vs ⌘Enter) are the same chord; the row shows the name of the code that was recorded.
• While a row is recording, the next chord anywhere on the page goes to the recorder — not just keys pressed inside the composer.
• The mapping is a browser-profile preference: it does not travel with the session, and another browser/OS profile starts at the defaults.
