Subliminal priming?

Is that like when a major news network runs the caption "Mark Foley (D-FL)" 
under images of a disgraced ex-congressman (who is actually Republican)?


To answer your question, I've tried using "milliseconds" and "ticks" in 
combination with the "wait" and "send xxx in nn" commands and had very 
inconsistent results controlling on-screen animation/activity when the 
values were small. Perhaps if the script were extremely simple and it was a 
virgin install of the operating system, the results would be more 

If you are trying to strictly control the amount of time a subliminal 
message appears on-screen (for example to determine the threshold of 
perception) I am not sure you will be able to do this accurately, to 
scientific/laboratory standards, with Rev.

You will also need to consider the monitor refresh rate, which could be 
anything from 50 Hz to 120 Hz. I do not believe this can be controlled or 
sensed from within Rev.
