Has anyone else seen the program, "Blitz" ???

Ok, now does anyone want to speculate on how it does what it does so fast?
I have a few speculations of my own...

In the "Fast Key" mode, Blitz seems to be checking for key UP and DOWN codes,
rather than the key itself.  So, I held down the down-arrow key and began
whizzing through a long file.  Then, I pressed the menu-button on the mouse.
The text of my file kept whizzing past me even though I was holding down the
menu-button.  I went and pulled down some menus.  As soon as the menus formed,
they were whizzed right off the screen along with the rest of the text that
was still whizzing by.

This kinda confirmed my suspicions that Blitz wasn't emitting text through any
of the Amiga routines that know about LockLayers().  My only guess is that
Blitz is getting the pointer to the Font data itself and just making the
blitter blit it.

Since Blitz is set up in it's own screen, I suppose doing this would not be
a super-hard thing to do.  

Oh, for those of you who haven't seen Blitz:

It took me 21 seconds to TYPE a four page file from DOS.  With Blitz, you can
run through a 104 page file in 26 seconds! (I did!)  Wow!  That's pretty cool.

Does anyone want to comment on my speculations about how Blitz works?  Want to
add your own?  Please do.
