Hello.

It could say, ``You will see the number @code{4} (and other details in a list) appear in the echo area.''

    8cda6f8f (Glenn Morris             2007-09-06  1257) If you are reading this inside of GNU Emacs in Info, here is how you can
    8cda6f8f (Glenn Morris             2007-09-06  1258) evaluate such a list:  place your cursor immediately after the right
    8cda6f8f (Glenn Morris             2007-09-06  1259) hand parenthesis of the following list and then type @kbd{C-x C-e}:

    8cda6f8f (Glenn Morris             2007-09-06  1265) @c use code for the number four, not samp.
    8cda6f8f (Glenn Morris             2007-09-06  1266) @noindent
  ef7dbdf5 (Paul Eggert              2015-09-15  1267) You will see the number @code{4} appear in the echo area.  (What
    ef7dbdf5 (Paul Eggert              2015-09-15  1268) you have just done is evaluate the list.  The echo area
    ef7dbdf5 (Paul Eggert              2015-09-15  1269) is the line at the bottom of the screen that displays or echoes
    8cda6f8f (Glenn Morris             2007-09-06  1270) text.)  Now try the same thing with a quoted list:  place the cursor

    ;; `C-x C-e' produces in the echo area `4 (#o4, #x4, ?\C-d)'
    ;; `C-u C-x C-e' produces `4'
