I believe that I have figured it out.  I was able to set up the scanner with 
a "Intercharacter Delay" which places a short (ms) delay between the 
transmission of each character of scanned data.  I am now able to use 
"o+filename" (ex: otest) to create my barcode and only scan once to open, 
populate and load the program.  This will save a lot of time.
Thanks for the help!

It's probably not that the kernel doesn't listen to the keyboard, but
the timing of the control transfer to the file widget. The 'o' causes
the widget to pop up, but it takes a little time, and the focus
doesn't transfer to the file dialog right away. This also means that
the first few characters of the filename still go to the command line
and are interpreted as commands, which could maybe explain your
mysterious jogs.

There is no reliable solution to this: you can't control timing of the
focus transfer. In normal usage, you press the command and start
typing the filename when you get the visual cue of the window popping
up. You could try a hack of including a generous amount of spaces or
some other character that doesn't do anything important in both the
interpreter and the file dialog (tabs?newlines?Ctrl-L?)
between the 'o' and the filename.
