feat(web): add usage page keybinding

[jakeleventhal]

NOTE FROM HUMAN

This PR is much more useful in conjunction with #9263 - I added this PR because if provider limits are there, its something I find myself checking frequently.

The rest of this was AI generated

Opening the Usage page currently requires the sidebar or the command palette. This adds a configurable usage.open command that defaults to mod+u and stays inactive while the terminal has focus. The palette's "Open usage" action shows the binding like other palette actions.

A capture-phase listener in CommandPalette resolves the shortcut and navigates to /usage, so it runs before the composer's underline shortcut can consume mod+u. Web and desktop share the behavior. The keybinding contract, default synchronization, focused tests, and user docs are updated with it.

Validation:

• vp test run packages/contracts/src/keybindings.test.ts apps/server/src/keybindings.test.ts apps/web/src/keybindings.test.ts apps/web/src/components/settings/KeybindingsSettings.logic.test.ts
• vp run -F @t3tools/contracts -F @t3tools/shared -F @t3tools/web -F t3 typecheck
• focused vp lint
• focused vp fmt --check

No visual changes.

Note

Add usage.open keybinding with default modifier-plus-U shortcut

• Registers usage.open as a static keybinding command and maps it to modifier-plus-U (outside terminal focus) in the default bindings
• Implements a global keydown handler in CommandPalette that resolves the shortcut, closes the palette, and navigates to /usage; the binding is skipped when the event is already prevented or composing
• Extends the shortcut-resolution context with modelPickerOpen so other bindings also receive the current model-picker visibility state
• Updates tests for command options, default bindings, and rule parsing; documents the shortcut in keybindings and usage docs
• Risk: existing consumers of the CommandPalette shortcut-resolution context now receive an additional modelPickerOpen field — check CommandPalette.tsx for any resolver that does not tolerate the extra field

• line 521: usage.open is resolved without editableFocus in its context. A user can configure the new command with the documented condition when: "editableFocus", but resolveShortcutCommand defaults that omitted flag to false, so the binding never opens Usage while a text field/composer is focused and no other handler dispatches usage.open.

Note

Low Risk
Low-risk UX addition; outside terminal focus the app now captures mod+u, which could conflict with any other in-app use of that chord.

Overview
Adds a configurable usage.open command (default mod+u, inactive while the terminal has focus) so the Usage page is reachable from the keyboard instead of only the sidebar.

The command is registered in the keybinding contract and shared defaults, wired in the global shortcut listener in CommandPalette to close overlays and navigate to /usage, and covered by contract/server/web tests plus user docs for keybindings and usage.

Summary by CodeRabbit

• New Features
  • Open the Usage page with mod+u when the terminal isn’t focused. You can customize this shortcut in Settings → Keybindings.
  • The shortcut works from the command palette and respects terminal, preview, and model-picker context.
• Documentation
  • Added instructions for opening Usage from the sidebar, command palette, or keyboard shortcut.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds a shipped default mod+u shortcut that intercepts key events and navigates users to the Usage page, while also exposing the command in customization and the command palette. Because it changes product defaults and user-facing runtime behavior, human review is warranted.

📝 Walkthrough

Walkthrough

The PR registers usage.open as a keybinding command, adds a default mod+u binding when the terminal is not focused, and routes the shortcut to /usage. It also updates keybinding tests and Usage page documentation.

Changes

Usage shortcut

Layer / File(s)	Summary
Register the usage.open binding packages/contracts/src/keybindings.ts, packages/shared/src/keybindings.ts, packages/contracts/src/keybindings.test.ts, apps/web/src/components/settings/KeybindingsSettings.logic.test.ts	The keybinding contract accepts usage.open. The default binding is mod+u when the terminal is not focused. Tests cover command parsing and command options.
Handle the shortcut and navigate apps/web/src/components/CommandPalette.tsx, docs/user/usage.md	CommandPalette resolves usage.open using terminal, preview, and model-picker context. When it matches, the handler prevents the default action, stops propagation, closes the palette, and navigates to /usage. The documentation describes the shortcut and how to customize it.

Merge Risk: 🔵 Low · up to 9377c

A matching shortcut during text composition can interrupt input and navigate away. This is a bounded interaction issue; otherwise the change appears mergeable.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 9377c

The shortcut opens the existing Usage page without adding a new permission or data-changing operation. Its behavior in every editable or shortcut-capturing control is not fully established.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The added trigger is a keyboard event within the running app and reaches an existing client route. The changed handler shows no new service call, permission grant, or persistent data write.

Trust Boundaries and Controls

• observed — A neighboring global keyboard handler rejects shortcut-capturing targets and supplies editableFocus; the new Usage handling does neither. Whether those controls consume the event first remains unverified.

Ignore composing keydown events before resolving shortcuts.

resolveShortcutCommand does not filter event.isComposing. A composing keydown that matches usage.open can prevent the event, close the palette, and navigate to /usage.

🐛 Suggested fix

     const onKeyDown = (event: globalThis.KeyboardEvent) => {
+      if (event.isComposing) return;
       if (event.defaultPrevented) return;
