Hmm actually I think you meant b9460d (AM button) for fast forward. That seems to cut the delay in half (as expected.)

So it sounds like if there is a 1s delay for an overloaded button like FF, REW this delay becomes two seconds.

My Info button is defined like this:

AD5241.L=20df14.L ; info
AD5241=20df14 ; info

When I tap it, I it acts like info. When I hold it however, it changes the info after one second, and then shows track details after two seconds.

So I guess what I'm saying is that maybe the side effects of this implementation outweigh its advantages... Maybe it was a bad idea?
