Re-read a panel                                 
 This option allows you to re-read the information in a panel.
 The following lists the information re-read for different
 panels, and mentions why you might want to use this option:

   Full/Brief:  Re-read the directory.  This is useful when
                you're looking at a floppy-disk drive and you
                change the disk in the drive.

         Tree:  Re-scan the disk.  The Commander normally
                keeps the directory information in a file
                called \treeinfo.ncd for fast access.  If you
                use the DOS mkdir or rmdir commands, or if
                another program creates or removes a
                directory, you can use this option to update
                the tree.

   Note:  Control + R will re-read the active panel.
