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.
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.
When the composer is open:
Ctrl+R,Ctrl+Shift+R,Ctrl+Fare blocked to prevent accidental replies- Other global shortcuts continue to work
When viewing Unified Inbox and replying:
- Reply uses the account associated with the selected message
- This ensures replies come from the correct email address
