thank you, but I need certainty! :-)

My scenario:
...
lock screen for visual effect
set the effectrate to 300
go next cd
unlock screen with visual wipe left very slow
...

and on the "next card"  I need to measure the time until the 
user hits a certain key (1 or 2) on the keyboard like this:
-------------------------
## Script of the "next" card:
local tMillisecs

on opencard
   put the millisecs into tMillisecs
end opencard

on keydown tKey
if tKey = 1 OR tKey = 2 then
   put the millisecs - tMillisecs into tDuration
...

You get the picture, so I need to measure this precisely!



Best

Klaus
