Behavior Notes

Pane Focus Model

The UI has three panes with visual focus indication:

Sidebar - Account/folder list
Message List - Conversations in selected folder
Conversation Viewer - Selected conversation content

Clicking a pane focuses it. Focus is indicated by a subtle border flash animation.

Alt+Up/Down navigates through all folders in visual order:

Unified Inbox (All Inboxes)
Individual account inboxes under Unified Inbox
Account 1 header
Account 1 folders (if expanded)
Account 2 header
Account 2 folders (if expanded)
… and so on

Collapsed accounts show only their header (not folders) in navigation.

Message Actions Hierarchy

Action shortcuts (Delete, Archive, Spam, Star, Read/Unread) follow this priority:

Checked messages - If any messages are checked (via Space or Shift+navigation), actions apply to ALL checked messages
Keyboard-focused message - Otherwise, actions apply to the message that’s currently focused in the message list (the one with keyboard highlight from j/k navigation)
The message being viewed in the conversation pane is independent - you can navigate to and delete a different message without opening it first

First Escape clears checkboxes, second Escape closes the conversation viewer.

Composer Blocking

When the composer is open:

Ctrl+R, Ctrl+Shift+R, Ctrl+F are blocked to prevent accidental replies
Other global shortcuts continue to work

Ctrl+Tab cycles forward through the rail items: Mail → first enabled extension → next → wrap to Mail. Ctrl+` cycles backward. Both are no-ops when no extensions are enabled (only Mail in the rail). Active extension is persisted across launches.

Composer state is preserved across switches: switching to an extension and back does not unmount or clear the composer.

Unified Inbox

When viewing Unified Inbox and replying:

Reply uses the account associated with the selected message
This ensures replies come from the correct email address

Extensions

Extension shortcuts only fire when the corresponding extension is the active rail pane (selected via Ctrl+Tab / Ctrl+`). They never trigger while Mail is active — so shortcuts that overlap with Mail’s (like Ctrl+N, Ctrl+Shift+A, Ctrl+Shift+S) are unambiguous: the active rail decides which handler runs. For example, Ctrl+Shift+A syncs accounts in Mail, syncs all calendar sources in Calendar, and syncs all contact sources in Contacts.

Pane-local navigation (Up/Down/J/K, Enter, Space, Alt+H/L for pane cycling, Alt+Up/Down for sidebar) uses the same kit-shared predicates Mail does — they’re listed per-extension below for completeness, but they’re not extension-specific re-implementations.

Calendar

Navigation (pane cycling)

Shortcut	Action
`Alt+Left` / `Alt+H`	Focus previous pane
`Alt+Right` / `Alt+L`	Focus next pane

Date / view navigation

Shortcut	Action
`T`	Jump the calendar view to today
`←`	Previous view-unit (prev month / week / day)
`→`	Next view-unit (next month / week / day)
`Alt+M`	Switch to month view
`Alt+W`	Switch to week view
`Alt+D`	Switch to day view
`Alt+A`	Switch to agenda view

Actions

Shortcut	Action
`Ctrl+N`	Open the new-event composer
`Ctrl+R`	Sync all calendar sources
`Ctrl+Shift+A`	Sync all calendar sources (same chord as Mail’s “sync all accounts” — fires whichever handler matches the active rail)
`F`	Toggle focus mode for the selected event

The calendar sidebar uses checkbox toggles per calendar (not single-select navigation), so it doesn’t follow the kit’s J/K row-cycling pattern. Clicking a checkbox or row in the sidebar toggles visibility.

Contacts

Sidebar navigation (works from any pane)

Mirrors mail’s “Folder Navigation” shortcuts. These fire regardless of which contacts pane currently has keyboard focus — so you can scroll through addressbooks while the list or detail pane is focused.

Shortcut	Action
`Alt+Up` / `Alt+K`	Move to previous source / addressbook in the sidebar
`Alt+Down` / `Alt+J`	Move to next source / addressbook in the sidebar

Pane cycling

Shortcut	Action
`Alt+Left` / `Alt+H`	Focus previous pane (detail → list → sidebar)
`Alt+Right` / `Alt+L`	Focus next pane (sidebar → list → detail)
