3.7.9 Previous File in Time
This option causes Isis to look for the next file in your current directory that
contains the previous earlier navigation date and time, if such a file exists.
The keyboard shortcut for this action is ALT+[Page Down].
3.7.10 Specify Search Wildcard
As an aid to narrowing your search for a previous or next file to play back,
choose this option. You can specify how each file name will start and/or end.
For example, specifying LINE*.XTF will cause Isis to only consider XTF files
which begin with the word LINE when searching for a file. Using ???E*.* will
match files which start with any three characters and have an E in the fourth
character of the name. If you check the Secondary wildcard box in this
dialog box, you can make Isis search for an additional set of files at the
same time.
3.8 Page Up
In a file being played back, this option repositions the file 500 pings ahead
(toward the end of the data file) from its current position. If fewer than 500 pings
remain before the end of the file is reached, the system positions the file at the
end of the file. (You are prevented from positioning the file past its end.) The
[Page Up] key is a shortcut to this command.
3.9 Page Down
In a file being played back, this option repositions the file 500 pings back (toward
the start of the data file) from its current position. If fewer than 500 pings remain
before the beginning of the file is reached, the system positions the file at the
beginning of the file. (You are prevented from positioning the file ahead of its
beginning.) The Page Down key is a short cut to this command.
Note: If Go back to Start is selected in the File→At End of File menu setting,
and you press Page Down near the end of the file, playback will jump to
the start of the current file.
3.10 At End of File
At End of File has two options: Go Back to Start or Go to Next File in Time.
Go Back to Start causes Isis to replay a file continuously. When the end of the
file is reached, Isis returns to the start of the file. Select the command from the
