Adds keyboard shortcuts to change folder, move/copy messages, with folder name auto-completion (using only the keyboard). Same for tags. Also includes a system of rules to suggest a target folder for saving messages; re-creates Eudora's Alt-Click; facilitates navigation in the 3-pane window; makes it easy to change between To/Bcc/Cc fields in the composer; facilitates tag-oriented operations. All that with the keyboard only!
Other keyboard actions include: changing focus
between panes, scroll the message while keeping the focus on the thread pane, changing header in the composer (To/Cc/Bcc), adding an attachment, hide the folder view.
Save time and get back the productivity you were used to with mutt/pine/eudora!
