+Just as you can use abbreviations to specify a class of
+filenames, you can use abbreviationss in the editor to recognize
+strings in the substitute command.  Unfortunately, the
+characters used in the editor are quite different from the
+ones used in the file-name handler to specify patterns.
+(Sorry about that, but that's the way the world is.)
+
+The symbol for 'any character' is '.' and this will
+match any single letter or other character in a line.
+For example, 
+  s/a./bc/
+looks for an 'a' followed by anything, and changes those
+two letters into 'bc'.  Try this sequence and note
+what happens.
