Select/Unselect/Invert group                  Gray +, -, *, ^M
 These  commands  allows you to select, unselect  and  invert
 selection for a group  of  files.  A dialog box appears into
 which  you  can  type a  DOS  wildcard characters to specify
 which  files  to  select, unselect or invert.  For  example,
 "*.doc" selects all the files with the .doc extension.

Restore Selection
 This  command  can be used to restore a previously  selected
 group.  So if you have just copied a group of files and want
 to  copy  them  again to somewhere else  you can restore the
 selection group and repeat the copy command.

DOS Wildcard Characters
-----------------------
 DOS file names have two parts: the name (which  can be up to
 8 characters) and  the  extension (which  can  be  up  to  3
 characters)  with  a  period   in   between.  For   example,
 "filename.ext".

    *   Matches any characters for the  rest of the  name  or
        extension.  "a*" will  match "a", "ab", and "abc", as
        well as many others.  `*' applies just to one part of
        the  file  name, so "a*"  will not match "ab.c".  Use
        "a*.*" to find all files that start with `a' and have
        any extension. (Note: "*a" will match  any  name, and
        not just names with an `a' at the end  as  you  might
        expect.)

    ?   Matches one character.  So "a?" will match "a", "ab",
        "ac", etc. "????" will match any name with up to four
        characters,  and "a*.??z" will  match  any  file name
        starting with `a' and ending with `z'.

   Notes:
     .  You can use Select group in conjunction with Unselect
        group, Invert group  and  Ins (to  select/unselect  a
        single file) to mark any group of files.

     .  Select group and Invert group commands  act  on files
        only,  but  Unselect group  command acts on files and
        directories.
