Select/Deselect group                          
Gray +, Gray - and Gray * on the numeric keypad.

 These three commands allow you to select and deselect a group
 of files.  With Gray + and Gray -, a dialog box appears
 where you can specify groups of files using DOS wildcards. For
 example, "*.doc" selects all the files with the .doc extension.

 The Gray * key inverts the current selection by deselecting
 all the selected files, and selecting all the files not
 previously selected.

   Note:  You can use Select group in conjunction with
          Deselect group (Gray -) and Ins
          (to select/deselect a single file) to mark any group
          of files.

Restore Selection
 This command can be used to restore a previously selected
 group. If you have just copied a group of files to a directory
 and want to recopy them elsewhere, restore the selection group
 copy them again.
