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)?

[Apologies!]

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 
consistent.

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.
