                      2: You can use other commands than 'p' with these
                      3: context search addresses, of course.  For example,
                      4:  /abc.e/s/ab/xx/p
                      5: will
                      6:  (1) search for the next line containing the
                      7:      expression "abc.e", which matches any line that
                      8:      has an 'a', then a 'b', then a 'c', then
                      9:      anything, then an 'e' (so that it matches
                     10:      "abcde", "abcxe", "abc9e", but not "abceq");
                     11:  (2) on that line, change the first "ab" to an "xx".
                     12: Edit file 'county'; find the line with 'pacific' on it
                     13: and change it to 'ocean'.  Then rewrite the file
                     14: and type "ready".
