feat: add markdown formatting shortcuts - #6254
Conversation
WalkthroughThe editor now supports Meta/Ctrl shortcuts for inline formatting, headings, lists, links, code, and blockquotes. Blockquote toggling handles selected nonblank lines, compact quote markers, indentation, blank lines, and mapped selections. Formatting dispatch is shared between direct commands and the formatting controller. Tests cover command parity, shortcut behavior, link selection, and quote toggling. Suggested reviewers: Merge Risk: 🔵 Low · up to The PR adds Markdown formatting shortcuts, but mixed quoted and unquoted selections can receive duplicate quote markers and the macOS bullet-list shortcut is currently unhandled. These are localized, low-impact correctness and usability issues that are mergeable with explicit owner follow-up. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Greptile SummaryThis PR adds keyboard shortcuts for inline and block Markdown formatting and extracts a shared formatting dispatcher for toolbar and shortcut execution.
Confidence Score: 3/5The PR should not merge until the link shortcut can create an editable, usable destination and the blockquote toggle correctly handles existing valid quote markers. The new reachable shortcut inserts an empty link without offering URL entry, while the new quote toggle adds nesting instead of removing valid blockquotes that omit the optional marker space.

| Filename | Overview |
|---|---|
| web/src/components/MemoEditor/Editor/extensions.ts | Adds formatting key bindings and blockquote toggling, but link creation has no URL-entry path and valid unspaced quote markers are misclassified. |
| web/src/components/MemoEditor/Editor/formatting.ts | Extracts the shared command dispatcher; its existing empty-URL fallback becomes user-reachable through the new shortcut. |
| web/tests/editor-formatting.test.ts | Verifies that direct and controller-based formatting dispatch produce the same result. |
| web/tests/editor-keys.test.ts | Covers the new shortcuts but codifies an empty link destination and omits valid blockquote marker variants. |

On a US-layout macOS keyboard, Shift+7 is &, not the platform-specific location of -; CodeMirror's shortcut names use the unshifted digit key. Consequently Cmd+Shift+8—the macOS counterpart of the Ctrl+Shift+8 binding immediately below—does nothing, while Cmd+Shift+7 unexpectedly creates a bullet list. Use Meta-Shift-8 here as well.

When Cmd/Ctrl+J is invoked outside an existing link, this calls the link command without a URL context. The command therefore inserts [text]() (or []() with no selection) and places the caret after the entire construct, so subsequent typing is outside the link and the shortcut cannot directly enter either a label or URL. The shortcut should leave/select an editable placeholder inside the generated link or invoke a URL-entry flow.

For valid CommonMark blockquotes written without the optional space, such as >quoted, this predicate reports the line as unquoted. Pressing the blockquote shortcut then produces > >quoted, nesting the quote instead of toggling it off. Detect the > marker independently of whether it is followed by a space and remove the marker's actual width.

Do not duplicate quote markers in mixed selections.
When allQuoted is false, this branch adds "> " to every target, including lines that already have a quote marker. A selection such as > quoted\nplain becomes > > quoted\n> plain.
Add markers only to targets where quoteMarkerLengths[index] === 0. Keep the existing removal behavior when all targets are quoted.
Proposed fix
- const changes = targets.map((line, index) => {
+ const changes = targets.flatMap((line, index) => {
const indent = leadingWhitespace(line.text);
+ if (!allQuoted && quoteMarkerLengths[index] > 0) return [];
- return allQuoted

Had to pick cmd/ctrl j for creating links, didn't want to override the global cmd/ctrl k.
