and pressing <Enter>, or by pressing the first letter of the menu label.  To
abort a partial command, press <Esc>.

%%%FILES                       Examine and Modify Disk Files

Use the <Pg Up> and <Pg Dn> keys to go toward the beginning or end of the
file, respectively, in screen units.  <Home> jumps to the beginning of the
file, and <End> jumps to the end of the file.  Note that the last file sector
may have "garbage" in it, since the portion of the sector following the last
character in the file is not cleared when the file is written.

%%%SECTORS                       Examine and Modify Disk Sectors

Use the <Pg Up> and <Pg Dn> keys to examine previous sectors (smaller sector
numbers) or next sectors, respectively.  The BOOT SECTOR of a disk is always
sector 0; the first File Allocation Table (FAT) starts at sector 1.  The root
directory follows the FATs, and the data area follows the root directory.
The INFO function from the Main Menu tells which sectors the root directory
and data area start in.

The first cluster displayed may or may not be available for recovery as DOS
may have already reused the cluster.  Use the <F2> key to add a cluster to
the recovered file, or <F3> to remove the most recently added cluster from
the disk.   read the previous or next free clusters, and <Pg Up> and <Pg
