\\[kom-edit-send]   sends the text when you are ready. The buffer will be
	  deleted if (and only if) the server accepts the text.
\\[kom-edit-quit]   aborts the editing. You will get back to the LysKOM buffer.

\\[kom-edit-show-commented]   shows the commented text in a temporary buffer.

\\[kom-edit-add-recipient]   asks for another recipient and adds him to the header.
\\[kom-edit-add-copy]   as \\[kom-edit-add-recipient] but adds him as copy-recipient.

\\[kom-edit-insert-commented]   inserts the commented of footnoted text.
