feat(web): switch the composer between rich text and Markdown source from a button or mod+/#26777
Before: on main the composer footer has only the attach button on the left
After: a feather button sits right of attach, rich text showing
After: button pressed, the same draft shown as raw Markdown
Settings → Keybindings lists Composer: Toggle Rich Text on Ctrl /
Checking the exact Markdown a draft will send meant going to Settings → Chat → Rich text composer and back. The composer now has a feather button right of attach, and a mod+/ shortcut, that flip that same setting, so the draft switches between styled text and literal **markers** in place. The button is the same ghost icon button as attach, pressed while the source is shown, and Settings stays in sync because everything writes composerRichTextEnabled. The shortcut is a configurable composer.toggleRichText binding (!terminalFocus), listed in Settings → Keybindings and shown in the button's tooltip; a held key flips once. This brings over the toggle from chrisdeeming's #12452 / #14676.
The editor already remounts on that setting and restores focus and caret, so no editor changes were needed: the button only swallows pointer-down to keep a focused editor focused. The button is hidden, and the shortcut does nothing, for pending questions that take a literal answer. The shortcut hydrates client settings before flipping, and does nothing while you type in a citation comment so the remount can't drop an unsaved comment; the button already saves that comment first, since clicking it closes the comment popover. The mobile app has its own composer and is unchanged.
Checked in the web dev client: the button and mod+/ both keep the draft, focus and caret in both directions, mod+/ works with focus outside the composer, a fast double press ends where it started, the mode survives a reload, an unsaved citation comment survives mod+/, Settings reflects the change, and the binding shows in Keybindings. Format, lint, typecheck (web, contracts, shared) and the keybinding tests pass. Desktop wraps the same web composer and was not run separately.

Approvability
Verdict: Needs Human Approval
Macroscope's review found this PR requires human approval — The composer gains a rich-text/Markdown toggle and a default mod+/ shortcut. The default keyboard-binding change requires human review, even though it reuses the existing composer preference.

Walkthrough
The composer footer adds a button to switch between rich text and Markdown source for non-literal answers. The composer also exposes a keyboard shortcut for this setting. Documentation and keybinding tests describe and verify the controls.

Merge Risk: External image Moderate · up to db2c6
Toggling Markdown mode while a citation comment is open can discard that unsaved comment, so flush or retain the draft before merging. On keyboard layouts where slash needs Shift, the new shortcut will not trigger; the footer button still works.

Explanation
The title names the main change: a composer control that switches between rich text and Markdown source, via a button or the mod+/ shortcut. It matches the changeset, which adds a toggle button, a configurable composer.toggleRichText keybinding, and docs for both. The title uses the conventional commit form and plain language.
Full details: Description check
Explanation
The description follows the template's main sections only in part. It has no Problem section, and no separate Change section. It covers the change in detail, but it does not state the problem as a bug or request. Scope and approval is weak: it cites chrisdeeming's
#12452/#14676as the origin of the toggle, but it does not link a triaged issue or a maintainer approval comment, and it does not explain why the change qualifies as focused configuration of an established capability. Verification is strong: it lists manual checks in the web dev client with observed results, shows before/after screenshots, and includes a recording. It notes what was not run (desktop). The template also asks for the model and harness that did the work; the description says 'Written by claude-opus-5-5' and names Claude Code, which partly satisfies this.Resolution
Add a Problem section that states the problem in a sentence or two, with expected behavior and reproduction steps. Add a Change section that explains how the change addresses that problem. Fill in Scope and approval: link the triaged issue or the discussion with maintainer approval (including the approval comment), or explain why the change qualifies as focused configuration of an existing capability (the composerRichTextEnabled setting). Then state whether the referenced
#12452/#14676work has maintainer approval. Keep the existing Verification content and the model/harness line.

Note
Written by claude-opus-5-5 on behalf of Maria
Re the CodeRabbit note on ComposerRichTextToggle.tsx:23 (file chips stay chips in source mode): no change. The button flips the existing composerRichTextEnabled setting, the same one as Settings → Chat → Rich text composer. Plain mode has always kept chips as chips and turned only the formatting marks into literal text (#12160). Showing chip source in plain mode would change that existing setting for everyone, which is out of scope here. This PR only adds the entry point.

Handle shifted layouts for the new default shortcut.
The matcher uses both event.key and event.code, but requires an exact modifier match. On a German keyboard, / can produce key="/", code="Digit7", and shiftKey=true. The event contains /, but it does not match mod+/ because the binding does not include Shift.
The composer button remains available, and keybindings can be configured. This is a minor usability defect, not a blocked workflow. Use a non-symbol default or add an alternate binding for the shifted physical key.

Leaving mod+/ as is. The existing symbol defaults (mod+[, mod+], mod+=, mod+-) work the same way on layouts where the symbol needs Shift or AltGr, so this binding matches them. The binding is rebindable in Settings → Keybindings and the button beside attach does the same thing. Making the matcher layout-aware for every symbol binding would be its own change.
@maria-rcks Understood. mod+/ uses the same matching rules as the existing symbol defaults. The layout limitation remains, but I accept keeping this PR consistent with those defaults.
Would you like a follow-up issue for shared symbol-shortcut handling across keyboard layouts?

Make the shortcut retry hydration instead of returning silently.
composer.toggleRichText returns without action when client settings are not hydrated. A failed hydration leaves that state in place. The shortcut then does nothing and shows no feedback. The footer button calls updateClientSettings, which waits for hydration before it applies the patch. After a transient failure, the button can therefore succeed while mod+/ stays inactive. Hydration retries only when a settings subscriber mounts again.
Use persistClientSettingsUpdate for the flip. It hydrates first and then applies the toggle to the hydrated snapshot. The existing literal-answer guard stays unchanged.

✅ Confirmed as addressed by @maria-rcks
Note
Written by claude-opus-5-5 on behalf of Maria
Fixed in the latest commit: the shortcut now flips through persistClientSettingsUpdate, so it hydrates first and toggles the hydrated value. The literal-answer guard stays. Rechecked in the app: caret kept across both flips, a fast double press ends where it started, it works with focus outside the composer, and the mode survives a reload.
@maria-rcks The supplied code confirms that toggleRichText now uses persistClientSettingsUpdate, retains the literal-answer guard, and handles promise rejection. This addresses the finding. Thanks for checking caret preservation, rapid toggles, focus outside the composer, and reload persistence.

Preserve the open citation draft before toggling rich text.
When composer.toggleRichText updates composerRichTextEnabled, ComposerPromptEditorTiptap changes its key and unmounts the inner editor. An open citation comment keeps its unsaved text in refs. The popover close callback does not run during this unmount, so the draft can be discarded. Flush the active citation draft before the mode change, and retain it when saving is rejected.

Fixed in the latest commit. The shortcut now does nothing while focus is inside the citation comment editor, so the editor never remounts under an unsaved comment. The button path already commits the draft: clicking it closes the popover as an outside press, which saves the comment before the flip. Checked both in the app: Control+/ in the comment box leaves the mode, the popover and "keep me" untouched, and clicking the button saves "keep me" onto the chip, then switches to source.
@maria-rcks Thanks for the fix and the app checks. The shortcut guard prevents a remount while you edit a citation comment. Your button check confirms that the comment saves before the mode changes. This addresses the reported draft-loss scenario.
