The 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.

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.
