The Main Window

This page describes the main window — the window that opens when you launch the app — and how its pieces fit together. The detailed behaviour of each piece lives on its own page: the folder tree, the message list, reading a message, the compose window, and the look and layout options.

New here? Start with Getting Started.

Layout

The window is split into resizable regions by draggable splitters:

The main window: folder pane on the left, message list and reader pane on the right

  • The account badge sits at the very top of the left column — your avatar, account name, and e-mail address. Clicking it opens the Mailbox Manager.
  • The folder tree runs down the left (Navigating folders).
  • The Departments pane sits under it while you hold access to at least one department mailbox (The Departments pane).
  • A status strip closes the left column: the connection light and the most recent connection, transfer, or reconnect-timer event.
  • The right side stacks the message list (Navigating and searching messages) above the reader pane (Reading a message).
  • Notice banners and the search options row appear above the message list when there is something to show.
  • A status bar runs along the bottom.

The dividers between these regions are splitters — drag them to give a region more room. Their positions are remembered between sessions.

Selecting an app in the tree replaces the message list and reader pane with that app; see App folders.

Reader pane placement

View ▸ Reader Pane decides whether the reading pane is shown and where:

Menu entry Effect
Hidden No reading pane; messages open in a tab or window instead.
Vertical Pane beside the message list, the two side by side.
Horizontal Pane below the message list, the two stacked.

F8 toggles the pane between hidden and shown without going through the menu. With the pane hidden, messages open in a tab or window (see Opening a message).

Toolbars

One strip runs under the menu bar, holding the message actions on the left and the search box on the right.

The toolbar strip

Message actions operate on the current message or folder:

Button Icon Action
New Message new Open a fresh compose window (Ctrl+N). Its drop-down offers Using Same Recipients and Using Same Content and Recipients.
Reply reply Reply to the selected message (Ctrl+R).
Reply all reply-to-all Reply to sender and all recipients (Ctrl+Shift+R).
Forward forward Forward the selected message (Ctrl+L).
Delete del-msg Delete the selected message(s) (Del).
Print printer Print the selected message (Ctrl+P).
Contacts address-book Open your contacts: the Contacts app in a tab when it is installed, the address book dialog otherwise.
Options options Open the Options dialog (Ctrl+O).

The search box keeps the right-hand end of the strip to itself, so it stays reachable however narrow the window gets. It starts collapsed to a single search button; click that button (or press Ctrl+K) to expand it.

Connecting is driven from the connection light under the folder tree and from the Message menu.

Customising the toolbars

Right-click an empty part of the toolbar area for a menu that lays the strip out:

Group Choices
Main Toolbar Show or hide the toolbar strip entirely.
Button labels No text, Text Under Icon, Text Beside Icon
Toolbar edge Toolbar on Top / Left / Right / Bottom
Message actions Show message actions in the main toolbar or Show message actions beside the message

The last pair moves the message-action buttons between the main strip and a small toolbar attached to the reader pane; it applies while the reader pane is shown.

Undo and redo

Undo and Redo name the operation they act on, so the menu reads Undo Move 3 messages or Redo Delete message. They cover moving messages to another folder — from the context menu or by dragging onto a folder — copying messages into another folder, deleting messages to Trash, the Junk view's Move All to Trash, and the context menu's Mark as Read / Mark as Unread, Mark as Junk / Mark as Not Junk and Flag ▸. They also cover the folder context menu's New Folder, Rename Folder and Move ▸, moving a folder by dragging it onto a new parent, and Delete Folder on a folder that is not already in Trash. Each entry becomes available once there is something on it.

Undoing runs as ordinary background work, the same way the operation it reverses did, so it appears in the background-work indicator and the messages reappear in their original folder as it completes. Undoing a copy removes the copies it made; the messages it copied from stay where they are.

Undoing a read, junk or flag change puts every message back in the state it was in individually, not in one shared state: marking a mixed selection read and then undoing leaves the messages that were already read alone, and undoing a flag gives each message the colour it had before — or no flag, if it had none. A message you have changed again in the meantime keeps its newer state.

Undoing a folder operation puts the folder back the way it was: a rename gets its old name, a moved or deleted folder returns to the folder it came from, and a new folder is removed — permanently, and only while it is still empty. A folder whose name or place has since been taken by another folder is left where it is.

Each window keeps its own history, for as long as it is open; switching to another mailbox starts a fresh one.

The connection light

The coloured dot at the bottom of the folder pane is both a status display and the connection control:

Light Meaning
grey grey Not connected.
green green Connected.
red red The connection dropped or failed.

Click it for a menu with two mutually exclusive choices:

Choice Effect
Stay Connected Hold a connection: connect now, and keep retrying if it drops.
Stay Disconnected Stay offline: disconnect now, and stop any pending reconnect.

The pair records what you want the app to do, and holds that answer while it works on it: a connection that drops under Stay Connected keeps the selection and retries, turning the light red until it succeeds. The same pair sits in the Message menu, and Tools ▸ Connect (Ctrl+T) toggles the connection immediately.

Beside the light, a line of text reports the latest connection, transfer, or reconnect-timer event.

The status bar

The bar along the bottom carries:

  • A spinner on the left while the message list is still loading rows.
  • A rolling line of progress and status messages — sync activity, background transfers, errors, and confirmations.
  • The background-work indicator on the right: a compact progress bar for whichever queue is currently moving, with a +N marker when other queues are busy behind it. Click it for the full panel. See Background work.

Keyboard shortcuts

Beyond the per-action shortcuts listed above:

Shortcut Action
Ctrl+K Expand and focus the search box; again to collapse it
F8 Show / hide the reader pane
A letter or digit, on a folder tree Open the folder filter with it
Ctrl+1 … Ctrl+7 Jump to a prime folder: Inbox, Outbox, Sent, Drafts, Trash, Junk, Apps
Alt+1 … Alt+0 Jump to the 1st … 10th visible row of the message list
Ctrl+Q Quit (Linux and macOS)

Keyboards with dedicated mail keys are supported too: Reply, Forward, New, Print, and Close act on the current message, and the shifted Reply/Forward keys mean reply to all and redirect.

Your session is restored

Window size, splitter positions, toolbar placement, the current folder, and per-folder list layouts are all saved on exit and restored on the next launch. See Navigating folders for how the current folder is remembered.
