%dl
  %dt#keys Emacs key names:
  %dd
    | `C-x`      | means Control-x.                                          |
    | `C-x C-s`  | means Control-x, then Control-s.                          |
    | `C-x k`    | means Control-x, then k on its own (without Control).     |
    | `M-x`      | means Alt-x (Alt is called Option on some Mac keyboards).  
    |             The `M` stands for “Meta” which is presumably what the Alt
    |             key was called in the 70s.                                 |
    | `M-x help` | means press Alt-x, then type `help`, then press return.   |
    | `C-M-x`    | means Control-Alt-x                                       |
    | `S-x`      | means Shift-x                                             |
    | `s-x`      | means Command-x (the ⌘ Command key on Mac keyboards).  
    |              The `s` stands for “Super”, from the days when keyboards
    |              had Meta, Super, and Hyper keys.                          |
    | `<RET>` | means the Return or Enter key.                         |

    | `<DEL>` | means Backspace  
    |              (not to be confused with the delete-forward key)          |

    What Emacs calls your window-manager's windows. [[Emacs manual]](
    http://www.gnu.org/software/emacs/manual/html_node/emacs/Frames.html)

  %dt#windows Windows:
  %dd
    Subdivisions inside a Frame. [[Emacs manual]](
    http://www.gnu.org/software/emacs/manual/html_node/emacs/Windows.html)

  %dt#buffers Buffers:
  %dd
    The text you are editing. The difference between a buffer and a file is
    that their contents may differ until you save your changes; and some
    buffers aren't backed by files at all (e.g. a `*compilation*` or `*Help*`
    buffer). [[Emacs manual]](
    http://www.gnu.org/software/emacs/manual/html_node/emacs/Buffers.html)

  %dt#modeline Mode line:
  %dd
    Describes the buffer in the window above the modeline. Hover your mouse
    over each indicator in the modeline for a description. [[Emacs manual]](
    http://www.gnu.org/software/emacs/manual/html_node/emacs/Mode-Line.html)

  %dt#echoarea Echo area:
  %dd
    The line at the very bottom of the frame, used to display small informative
    messages. [[Emacs manual]](
    http://www.gnu.org/software/emacs/manual/html_node/emacs/Echo-Area.html)

  %dt#minibuffer Minibuffer:
  %dd
    The echo area when it is prompting for user input. [[Emacs manual]](
    http://www.gnu.org/software/emacs/manual/html_node/emacs/Minibuffer.html)

  %dt#region The point, the mark and the region:
  %dd
    The point is where the cursor is. Set the mark with `C-<SPC>`, move the
    point, and now the region is the area between point and mark. [[Emacs
    manual]](
    http://www.gnu.org/software/emacs/manual/html_node/emacs/Mark.html)

  %dt#killing Killing and yanking:
  %dd
    Killing = cutting. Yanking = pasting (sorry vi users!). [[Emacs manual]](
    http://www.gnu.org/software/emacs/manual/html_node/emacs/Killing.html)

  %dt#majormode Major mode or Editing mode:
  %dd
    A major mode is a customization of Emacs for editing text of a particular
    sort (e.g. a particular programming language). A buffer can only have one
    major mode active at a time. [[Emacs manual]](
    http://www.gnu.org/software/emacs/manual/html_node/emacs/Major-Modes.html)

  %dt#minormode Minor mode:
  %dd
    Multiple minor modes can be enabled at once; they add functionality ranging
    from syntax highlighting to automatic spell-checking to modifying the
    behavior of common Emacs commands. [[Emacs manual]](
    http://www.gnu.org/software/emacs/manual/html_node/emacs/Minor-Modes.html)
