How can I get a button to send a continuous signal for 3-4 seconds without having to hold it down for that period? The particular button in question is programmed to operate with my stereo preamp. The way it works is that it both controls the intensity of the display on the preamp-through short taps-or turns off the preamp through a long blast. I tried writing a macro which would send out signals at .1 second intervals, but that's not fast enough; the preamp needs to see a continuous signal.
