Lisp-based editing

Cutting and pasting with Emacs commands

They provide fine grain control over the text which is cut. For example, with a single keystroke you can cut a word, line, or expression.

They store multiple pieces of cut text. Whereas the Macintosh clipboard can hold only a single item, the Fred kill-ring can hold any number of pieces of text.

• Move to the start of the line containing "Hello, world!".
• Press Control k
  Control k is "kill line". It "kills" (removes) text from the cursor to the end of the line and places it on the kill ring. Subsequent Control k's will kill following lines.
• Type (format nil
• Press Control y
  Control y "yanks" (pastes) the top item from the kill ring into the editor window. The top line of the window should now read
  (format nil "Hello, world!"
• Continue editing.
  When you are done, the top line should read
  (format nil "Hello ~a" my-name)
