        !             2: So far all the addresses you have used have been
        !             3: either line numbers, '$', or '.' (or combinations
        !             4: thereof).  The most useful addresses are none of
        !             5: those, but are specifications of lines by content.
        !             6: Anything you can ask the substitute command
        !             7: to find in a line, you can ask the editor to find
        !             8: in a file.  In particular,
        !             9:  /xx/p
        !            10: is a valid command with a line address 
        !            11:  /xx/
        !            12: and the 'p' command operator.  The address
        !            13:  /xx/
        !            14: means 'the next line containing an "xx"'.
        !            15: So this command prints out the next line which
        !            16: has an "xx" on it.  Edit the file "text" and
        !            17: print the line which has "cat" on it.  Then
        !            18: leave the editor and type "ready".
        !            19: #create text
        !            20: This is a short list of
        !            21: things you might find
        !            22: in the Sears, Roebuck
        !            23: catalog.
