TLDR

On macOS, keyboard shortcut hints now use native modifier symbols ( for Ctrl, for Cmd, for Alt, for Shift) instead of the generic text format.

Closes #2227

Dive Deeper

The CLI keyboard shortcut panel and error retry hints displayed shortcuts like ctrl+y, cmd+v regardless of platform. On macOS, the convention is to use symbolic modifiers (⌃Y, ⌘V).

Changes:

  • packages/cli/src/ui/utils/shortcutFormatter.ts — New formatShortcut() utility that converts modifier names to macOS symbols when process.platform === "darwin"
  • packages/cli/src/ui/components/KeyboardShortcuts.tsx — Apply formatShortcut() to shortcut key display
  • packages/cli/src/ui/hooks/useGeminiStream.ts — Apply formatShortcut() to "Press Ctrl+Y to retry" hint messages
  • packages/cli/src/ui/utils/shortcutFormatter.test.ts — Tests for Mac symbol conversion, multi-part shortcuts, and non-Mac passthrough

Non-macOS platforms are completely unaffected — the formatter is a no-op on Linux/Windows.

Reviewer Test Plan

  1. Run on macOS — verify shortcut panel shows ⌃Y, ⌃C, ⌘V etc.
  2. Trigger an API error — verify retry hint shows ⌃Y instead of Ctrl+Y
  3. Run on Linux/Windows — verify shortcuts display unchanged (ctrl+y, ctrl+c)

@Br1an67 friendly ping — CI is currently red on all 9 Test (...) jobs, but the failures are not in the code this PR changes. They surface in packages/core/src/core/coreToolScheduler.test.ts with:

TypeError: this.toolRegistry.ensureTool is not a function

Root cause: the PR branch is based on main from 2026-04-18, and shortly after that point #3415 — test(core): update scheduler registry mock and a few related PRs (#3313, #3505) updated the scheduler tests to mock the new ensureTool API. Without those updates, the mock is missing the method and the test crashes.

Fix: rebase (or merge) latest main into this branch and push — no code changes needed on your side. Once CI is green I can take another look and merge.

Thanks for the contribution!

Reviewed the change. Direction is correct (native symbols on Mac, full no-op elsewhere keeps the blast radius tiny), but a few points worth addressing:

Main issues

1. .replace('Ctrl+Y', ...) couples the formatter to translation content

const retryHint = t('Press Ctrl+Y to retry').replace('Ctrl+Y', retryKey);

I checked all 5 locales that define this key (en/zh/zh-TW/fr/ca) and every one happens to contain the literal substring Ctrl+Y, so today it works. But this turns "every translation must contain the exact substring Ctrl+Y" into an implicit contract — the moment a translator writes Ctrl-Y, control+y, or transliterates the modifier, .replace silently no-ops and the raw Ctrl+Y survives on screen.

Note also that de.js / ja.js / pt.js / ru.js don't have this key at all — they fall back to the English key, which coincidentally still contains Ctrl+Y. That's accidental, not designed.

A safer pattern is interpolation:

t('Press {shortcut} to retry', { shortcut: formatShortcut('ctrl+y') })

with the locale strings updated accordingly (e.g. '按 {shortcut} 重试。').

2. Column-width calculation in KeyboardShortcuts.tsx wasn't updated

getShortcutWidth still uses shortcut.key.length (KeyboardShortcuts.tsx:72), but rendering goes through formatShortcut(shortcut.key):

'ctrl+y'.length === 6,  '⌃Y'.length === 2

On Mac this overestimates widths, so a layout that could fit in 3 columns may get downgraded to 2. The display still looks correct, but part of the UX win this PR is trying to deliver is being eaten by stale layout math. Either run formatShortcut inside getShortcutWidth too, or precompute a displayKey field on the shortcut.

3. Module-level isMac + vi.resetModules() is unnecessarily complicated

const isMac = process.platform === 'darwin';   // captured once at import time

The test has to use vi.resetModules() + dynamic import() to flip platforms. Reading process.platform inside the function would let the test be a plain synchronous case. This isn't on a hot path so the perf difference is negligible.

4. Two unrelated comments deleted in useGeminiStream.ts

The diff drops // Store error with hint as a pending item (not in history). and // Store error with hint as a pending item (same as handleErrorEvent). They look like incidental losses while editing nearby lines — unrelated to this PR's purpose and worth restoring.

Minor suggestions

  • Mac convention for Tab is : the test asserts 'shift+tab' → '⇧TAB', but Apple HIG would be ⇧⇥. Same for Esc → ⎋ and Return → ⏎. If we're going for "native symbols," extending the map to cover tab/esc/return/enter would be a natural follow-up. Not a blocker.
  • Test coverage gaps: multi-modifier combos (ctrl+shift+a⌃⇧A), uppercase input (Ctrl+Y, CMD+V), single-symbol keys (!///@ — current toLowerCasetoUpperCase path returns them unchanged, but no assertion locks that in).

Not blocking

  • The MAC_MODIFIERS[lower] truthy check is fine here (all values are non-empty strings); no need for hasOwnProperty.
  • Non-Mac is a complete no-op, so regression risk is low.
  • getExternalEditorKey returning 'ctrl+x' on both branches is a pre-existing oddity, not this PR's concern.

I'd suggest prioritizing #1 (i18n contract) and #2 (width calc); the rest are suggestions.

Two follow-ups on the review state:

Dismissed the prior auto-LGTM — the earlier /review bot approval ("No issues found. LGTM!") didn't catch the i18n / layout-width issues in the comment above, so I've dismissed it to reflect that the PR still has open comments to address.

CI is red, but it's not from this change. The failing test is packages/core/src/core/coreToolScheduler.test.ts with TypeError: this.toolRegistry.ensureTool is not a function. This PR only touches packages/cli/src/ui/.... ToolRegistry.ensureTool was added on main in #3297 and the scheduler mock was updated in #3415 — both landed after this branch's last CI run (2026-04-18). A rebase onto current main should clear it.

Downgraded from Approve to Comment: CI has test failures (pre-existing base branch issues in coreToolScheduler.test.ts, not caused by this PR).

[Suggestion] Help.tsx (lines 110-155) still renders shortcuts as hardcoded strings (Ctrl+C, Ctrl+L, Ctrl+O, Alt+Left/Right) without going through formatShortcut. On macOS, the bottom shortcut bar will show symbols like ⌃C, while the Help dialog shows Ctrl+C for the exact same shortcuts — a user-visible inconsistency.

Suggested fix: also route Help.tsx shortcut keys through formatShortcut().

Overall: clean implementation, no blocking issues. The i18n coupling and layout-width concerns previously raised by @wenshao remain valid and are not repeated here. — Qwen Code /review

[Nice to have] combo.split('+') cannot represent the + key itself (e.g., ctrl++ for zoom-in would silently mangle). No current shortcut uses + as a key, but consider documenting this limitation or switching to a regex-based parser that matches known modifiers and leaves the remainder as the key.

@Br1an67 heads up — this PR currently has merge conflicts with main and can't be merged as-is. Could you merge main in (or rebase) and resolve them when you get a chance?

Conflicting files:

  • packages/cli/src/ui/hooks/useGeminiStream.ts

The rest merges cleanly. Thanks!

@Br1an67 提个醒 —— 这个 PR 目前和 main 有合并冲突,暂时没法直接合入。方便的时候麻烦把最新的 main merge 进来(或 rebase)解决一下冲突。

Clean extraction of formatShortcut utility for macOS modifier symbols (⌃⌘⌥⇧). Dynamic import via vi.resetModules() correctly handles process.platform detection in tests. KeyboardShortcuts.tsx and useGeminiStream.ts properly consume the new formatter.

⚠️ CI is failing across all 9 platform/node combinations (Test checks). This appears to be a rebase-needed issue — the PR branch is based on an older main.

Downgraded from Approve to Comment: CI failing.

E2E Tmux Test Report — PR #2484

Tested on: Linux (Ubuntu, x86_64) | Branch: fix/mac-keyboard-shortcut-display at aa8428d60 | Build: symlinked node_modules (no full build)

Test Results

Test Description Result
1 UI component tests (src/ui/utils/shortcutFormatter.test.ts + src/ui/components/) PASS
2 CLI typecheck (tsc --noEmit -p packages/cli/tsconfig.json) PASS (with pre-existing infra warnings)

Details

Test 1 — UI component tests

Test Files  107 passed (107)
     Tests  1568 passed | 1 skipped (1569)

All 107 test files in the src/ui/components/ and src/ui/utils/shortcutFormatter.test.ts scope passed with zero failures. The new shortcutFormatter.test.ts (3 tests) validates:

  • Mac modifier key symbol conversion (ctrl+y -> ⌃Y, cmd+v -> ⌘V, alt+v -> ⌥V, shift+tab -> ⇧TAB)
  • Multi-part shortcut handling on macOS (esc esc -> ESC ESC)
  • Non-macOS passthrough (input returned unchanged on Linux)

Test 2 — CLI typecheck

2 errors (TS6305) — pre-existing, unrelated to this PR

Both errors are TS6305: Output file has not been built from source file for packages/core/src/utils/toml-to-markdown-converter.ts. This is because packages/core/dist/ was not built in this environment (symlinked node_modules, no npm run build). These errors are not introduced by this PR — they exist on any checkout without a prior build of packages/core.

PR Change Summary

4 files changed, +102/-5:

  • shortcutFormatter.ts (new, 51 lines): Pure utility that converts modifier key names to macOS symbols on darwin, passthrough on other platforms.
  • shortcutFormatter.test.ts (new, 38 lines): 3 tests covering darwin conversion, multi-part shortcuts, and non-darwin passthrough.
  • KeyboardShortcuts.tsx (+2/-1): Wraps shortcut key display through formatShortcut().
  • useGeminiStream.ts (+8/-4): Replaces hardcoded Ctrl+Y in retry hints with formatShortcut('ctrl+y').

Verdict

PASS — All 1568 tests pass. The 2 typecheck warnings are pre-existing infrastructure issues unrelated to the PR changes. The new formatShortcut utility is clean, well-tested, and correctly scoped to macOS only.

Thanks for the PR, @Br1an67!

Template: all essential sections present (TLDR, Dive Deeper, Reviewer Test Plan, Testing Matrix, Linked Issues) ✓

Problem: real and well-documented. Issue #2227 includes a screenshot showing ctrl + Y on macOS where native symbols (⌃Y) are expected. The fix addresses an observed platform-convention gap, not a theoretical concern.

Direction: aligned with the project's platform-awareness goals. CLI tools respecting macOS keyboard symbol conventions is standard practice. No CHANGELOG precedent needed — this is a straightforward platform fix.

Size: 102 additions, 5 deletions across 4 files. All changes in packages/cli/src/ui/ — no core paths touched. Production code: ~64 lines (formatter + two call-site edits). Tests: 38 lines. Not applicable for core-module gates.

Approach: minimal and focused. A small formatShortcut() utility with a platform guard, applied at the two display points (keyboard shortcuts panel + retry hint). No scope creep. One observation for Stage 2: the .replace('Ctrl+Y', ...) pattern in the retry hint is somewhat fragile if the i18n string format changes, but it works for the English base string today.

Moving on to code review. 🔍

模板:所有必要章节齐全(TLDR、Dive Deeper、Reviewer Test Plan、Testing Matrix、Linked Issues)✓

问题:真实且有据可查。Issue #2227 包含截图,显示 macOS 上显示 ctrl + Y 而非原生符号(⌃Y)。修复的是一个已观测到的平台适配问题,非理论性关注。

方向:符合项目的平台适配目标。CLI 工具遵循 macOS 键盘符号规范是标准做法。无需 CHANGELOG 先例——这是一个直接的平台修复。

规模:4 个文件,102 行新增、5 行删除。全部改动在 packages/cli/src/ui/——未触及核心路径。生产代码约 64 行(formatter + 两个调用点)。测试 38 行。不触发核心模块门控。

方案:精简聚焦。一个带平台守卫的 formatShortcut() 工具函数,在两个显示点应用(快捷键面板 + 重试提示)。无范围蔓延。Stage 2 的一个观察点:重试提示中的 .replace('Ctrl+Y', ...) 模式在 i18n 字符串格式变化时有些脆弱,但当前对英文基础字符串是有效的。

Code Review

Independent proposal: To show macOS keyboard symbols (⌃⌘⌥⇧) instead of text modifiers, I'd create a small platform-guarded formatter function, apply it at the shortcut display points, and mock process.platform in tests.

Comparison with PR: The PR matches this approach exactly. formatShortcut() in shortcutFormatter.ts is clean — splits on whitespace for multi-part shortcuts, + for combo keys, maps four modifiers via a lookup table. The isMac module-level constant is fine for a CLI tool (platform doesn't change at runtime).

Reuse check: no existing formatter for platform-specific keyboard display in the codebase. The utility is justified and not duplicated elsewhere.

Findings:

  • .replace('Ctrl+Y', ...) fragility — the retry hint in useGeminiStream.ts does t('Press Ctrl+Y to retry').replace('Ctrl+Y', formatShortcut('ctrl+y')). This works for the English base string but will silently fail if a translation changes the format (e.g., CTRL+Y or rephrased). Not a blocker today, but worth noting as technical debt for when the i18n system matures.

  • Scope of shortcut formatting — the grep shows many other Ctrl+... strings in i18n translations (auth prompts, cancel hints, toggle shortcuts). This PR correctly scopes to the two user-facing display points (shortcuts panel + retry hint). Follow-up PRs can cover the rest.

No critical bugs, security issues, or AGENTS.md violations found.

Testing

Unit tests: 3/3 pass ✓

 ✓ src/ui/utils/shortcutFormatter.test.ts (3 tests) 10ms
   ✓ converts modifier keys to Mac symbols on darwin
   ✓ handles multi-part shortcuts on darwin
   ✓ returns input unchanged on non-darwin

 Test Files  1 passed (1)
      Tests  3 passed (3)

Runtime test (Linux): CLI starts and responds correctly with the PR code. On Linux, formatShortcut() is a complete no-op (returns input unchanged), so behavior is identical to main. The macOS symbol conversion can only be verified on a Mac — the CI matrix covers this.

$ npm run dev -- -p 'what is 2+2?'
> node scripts/dev.js -p what is 2+2?
DEV is set to true, but the React DevTools server is not running.

TUI rendering: the Ink/React TUI renders in the alternate screen buffer, which makes capture-pane unreliable for the shortcuts panel. The shortcuts panel component code is correct on inspection — formatShortcut() is applied to shortcut.key in ShortcutItem.

Merge conflicts: ⚠️ GitHub reports mergeStateStatus: DIRTY, mergeable: CONFLICTING. The author needs to rebase on main before this can be merged.

中文说明

代码审查

独立方案: 为显示 macOS 键盘符号(⌃⌘⌥⇧),我会创建一个带平台守卫的格式化函数,在快捷键显示点应用,并在测试中 mock process.platform

与 PR 对比: PR 完全符合这个方案。shortcutFormatter.ts 中的 formatShortcut() 实现干净——按空白符拆分多段快捷键,按 + 拆分组合键,通过查找表映射四个修饰符。isMac 模块级常量对 CLI 工具来说没问题(平台不会在运行时变化)。

复用检查: 代码库中没有现有的平台特定键盘显示格式化器。这个工具函数是合理的且没有重复。

发现:

  • .replace('Ctrl+Y', ...) 脆弱性 —— useGeminiStream.ts 中的重试提示使用 t('Press Ctrl+Y to retry').replace('Ctrl+Y', formatShortcut('ctrl+y'))。对英文基础字符串有效,但如果翻译改变了格式(如 CTRL+Y 或重新措辞),替换会静默失败。今天不是阻塞问题,但作为 i18n 系统成熟前的技术债务值得注意。

  • 快捷键格式化范围 —— grep 显示 i18n 翻译中还有许多其他 Ctrl+... 字符串(认证提示、取消提示、切换快捷键)。此 PR 正确地将范围限定在两个用户可见的显示点(快捷键面板 + 重试提示)。后续 PR 可以覆盖其余部分。

未发现关键 bug、安全问题或 AGENTS.md 违规。

测试

单元测试: 3/3 通过 ✓

运行时测试(Linux): CLI 使用 PR 代码正常启动和响应。在 Linux 上,formatShortcut() 是完全的空操作(返回输入不变),因此行为与 main 相同。macOS 符号转换只能在 Mac 上验证——CI 矩阵覆盖了这一点。

This is a clean, focused fix that solves a real problem. The author saw that macOS users get ctrl+y instead of ⌃Y in the CLI — a genuine platform-convention gap documented in #2227 with a screenshot — and shipped the minimum code to address it.

The implementation is straightforward: a small formatShortcut() utility with a platform guard, applied at exactly two display points. The test coverage is adequate (3 tests covering Mac conversion, multi-part shortcuts, and non-Mac passthrough). On Linux, the formatter is a complete no-op — zero risk of regression on non-Mac platforms.

My independent proposal matched the PR's approach exactly. I don't see a simpler path.

The .replace('Ctrl+Y', ...) pattern in the retry hint is the one thing I'd flag for the maintainer's awareness — it's fragile against i18n translation changes, but it works today and fixing it properly would require a deeper i18n refactor that's out of scope for this PR.

The only merge blocker is the unresolved merge conflict with main. The author needs to rebase before this can land.

Verdict: Code is good. Approving. 🟢

中文说明

这是一个干净、专注的修复,解决了真实问题。作者发现 macOS 用户在 CLI 中看到 ctrl+y 而非 ⌃Y——这是 #2227 中有截图记录的真实平台适配问题——并提交了最少的代码来解决它。

实现很直接:一个带平台守卫的 formatShortcut() 工具函数,精确应用在两个显示点。测试覆盖充分(3 个测试覆盖 Mac 转换、多段快捷键和非 Mac 直通)。在 Linux 上,格式化器是完全的空操作——非 Mac 平台的回归风险为零。

我的独立方案与 PR 的方案完全一致。没有看到更简路径。

重试提示中的 .replace('Ctrl+Y', ...) 模式是我会提醒维护者注意的一点——它对 i18n 翻译变化有些脆弱,但今天能正常工作,彻底修复需要更深层的 i18n 重构,超出了此 PR 的范围。

唯一的合并阻塞点是未解决的与 main 的合并冲突。作者需要在合并前 rebase。

判定: 代码没问题。批准。🟢
