dsh-ctrl-enter-send

Change the DSH composer's send key from Enter to Ctrl+Enter: Enter inserts a newline, Ctrl+Enter (Cmd+Enter on macOS) sends.

This fixes a concrete annoyance: when a Chinese IME is left in English mode, hitting Enter to start a new line sends a half-written prompt to the AI instead.

Install

This package is a DSH bundle distributed from GitHub. Install it with the DSH CLI (the official git-install path) and pin the release tag:

dsh plugin --profile <your-profile> add github:Geopanret/dsh-ctrl-enter-send#v0.1.0

• The plugin is a bundle: after installation it is appended to the profile's dsh.profile.bundles and activates the next time the page loads (a page refresh is enough; no DSH restart needed).
• Pinning the tag (or a commit: github:Geopanret/dsh-ctrl-enter-send#<sha>) is recommended, so later pushes cannot silently change what you run. Omit the #<ref> to track the default branch.
• No build step and no install-script approval are needed: this package is plain JavaScript and ships its built artifacts directly (client.js is the whole browser bundle). pnpm does not need an allowBuilds entry.
• Uninstall with dsh plugin --profile <your-profile> remove dsh-ctrl-enter-send (or from the Plugins page).

Compatibility: DSH >=0.2.0 <0.3.0 (declared in engines.dsh; tested on 0.2.1-rc.5).

Behavior

Action (focus in the main chat composer)	Before	After
Enter	send (or queue/steer while running)	newline (same as Shift+Enter)
Shift+Enter	newline	newline (unchanged)
Ctrl+Enter / Cmd+Enter	complementary delivery mode	send, exactly like the Send button (while running it follows Settings → General → busy-Enter: queue or steer)
Empty draft + Ctrl+Enter while running with queued messages	steer all queued messages	unchanged
Enter while the / or @ menu is open	select the highlighted item	unchanged
Enter while an IME is composing	confirm the composition	unchanged
Alt+Enter / Ctrl+Shift+Enter / AltGraph+Enter	ignored by the built-in keymap	unchanged
Other inputs (rename, inline message edit, settings, dialogs, question cards)	unchanged	unchanged

Clicking the Send button is unchanged; it and Ctrl+Enter use the same "plain Enter" gesture.

How it works

The plugin is browser-only. At page boot it installs one capture-phase keydown listener on window and rewrites the modifier flags of the event object, so the composer's existing keymap takes its own newline branch (Shift+Enter) or its own send branch (plain Enter):

• plain Enter → shiftKey = true (built-in newline);
• Ctrl/Cmd+Enter on a non-empty draft → ctrlKey/metaKey = false (built-in send);
• empty draft keeps the built-in Cmd/Ctrl+Enter steer-all gesture;
• menus, IME composition, Alt/AltGraph and every other input are left alone.

DOM contract used (DSH 0.2.1-rc.x): [data-composer-input], [data-composer-card], [data-trigger-menu], [data-composer-overlay], [data-composer-placeholder]. If any marker is missing, the plugin falls back to the built-in behavior instead of guessing — the worst case is "no change", never a mis-send.

If overriding the event flags is impossible in some environment, the plugin falls back to stopping the original event and replaying a synthetic Enter with the intended flags.

Known limitations

• The shortcuts cheat sheet/settings page still shows the built-in fixed rows "Enter = send" and "Cmd/Ctrl+Enter = complementary delivery". Those are read-only fixed entries owned by the built-in package and cannot be rewritten by a third-party plugin; the actual behavior is the one above.
• The old Ctrl+Enter "complementary delivery mode" semantics are replaced by the primary send gesture (that is the point of this plugin). The empty-draft "steer all queued messages" gesture is deliberately preserved.
• DSH upgrades may rename the data-composer-* markers; the plugin then silently reverts to the built-in keys. Update the selectors in client.js after such an upgrade.

Development

dsh plugin --profile <dev-profile> add /path/to/dsh-ctrl-enter-send

client.js is the whole client bundle (no build step); changes are picked up by DSH's client HMR watcher without restarting DSH. Host-side index.js changes need a restart.
