Keyboard ShortcutsThe following keyboard shortcuts are supported by default in the main window. Notice that many "universal" shortcuts (e.g. Ctrl+C to copy selected text to the clipboard, or Ctrl+F to open a "Find" dialog) are recognized by KMail, but are not documented here.
| Keyboard Shortcut | Action |
|---|---|
| Space | Scroll down in the current message. |
| → or N | Go to the next message in the current folder and display the message preview. |
| ← or P | Go to the previous message in the current folder and display the message preview. |
| Ctrl+Home | Go to the very first message in the current folder and display the message preview. |
| Ctrl+End | Go to the very last message in the current folder and display the message preview. |
| + | Go to the next unread message in the current folder. |
| - | Go to the previous unread message in the current folder. |
| C | Copy this message to another folder. |
| M | Move this message to another folder. |
| A | Reply to all recipients of this message (with quote). |
| R | Reply to sender with quote. |
| Shift+R | Reply to sender without quoting anything. |
| S | Launch the message search dialog. |
| T | Open this message in the composition window. |

| Ctrl+0 | Reset message Zoom factor to 100% (full size). |
| Ctrl+Alt+D | Toggle message structure display (below the message preview pane). |
| Ctrl+Shift+O | Create the tabbing toolbar (appears above the message list). |
| Ctrl+Shift+W | Remove the currently active tab from the tabbing toolbar. |
| Alt+↑ | Go to the previous folder in the folder list (if the folder list has focus). |
| Alt+↓ | Go to the next folder in the folder list (if the folder list has focus). |
| Ctrl+Home | Focus on the very first folder. Use Ctrl+Space to actually enter the folder. |
| Ctrl+End | Focus on the very last folder. Use Ctrl+Space to actually enter the folder. |
| Ctrl+Space | Enter the folder that has focus, i.e. the folder that you navigated to using Ctrl+Home or Ctrl+End. |
| Shift+H | Toggle between plain text and HTML (unless HTML has been preferred via the Settings dialog). |
| Shift+← & Shift+→ | Select messages sequentially in the message list, starting with the current message. |
For more keyboard shortcuts, take a look at the → dialog. If you're not happy with the defaults, you can change them!
Two mouse actions deserve mention here. First, you can select multiple noncontiguous messages to be processed all at once (e.g. copied, deleted, or moved) by pressing Ctrl and selecting them with the mouse button. Second, you can open a message in an external window by double-clicking an item in the message list. If the message is in the outbox, drafts, or templates folder, it will be opened in a composition window. Otherwise, it will be opened with the external message viewer, an abbreviated version of KMail's main window without the folder and message lists, and with shorter menus.
