try this in an otherwise empty .bat file:
@echo off
echo Try space and arrow-down
pause
echo 1
pause
echo 2
pause
echo 3
pause
echo 4
pause
echo 5
Why does any of the arrow keys trigger two consecutive pauses, while a space or a letter only triggers one?
Thanks!

I suspect pause is simply a call to _getch(), which blocks until it reads a single character of input, but which has the caveat “When reading a function key or an arrow key, each function must be called twice; the first call returns 0 or 0xE0, and the second call returns the actual key code.”
