Select/Unselect/Invert group                  Gray +, -, *, ^M
 These commands allows you to select, unselect  and  invert 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 to a
 directory and want to recopy them  somewhere  else  you  can
 restore the selection group and simply copy them again.

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".

    *   Match 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.)

    ?   Match  one  character.  So "a?" will match "a", "ab",
        "ac", etc. "????" will match any name with up to four
        characters.

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