bnokes@AAVViD,

Any reasonable number of commands can be attached to any button.

For example:

Receiver OFF
Delay 0.1 seconds
Screen command

I avoid long IR command strings because, if the user moves the transmitter during transmission, some commands may be lost. This is why I prefer RF.

Usually there is no need to wait between commands to different devices, sometimes one needs some "space" between commands. Each situation is unique. When I face unfamiliar devices, I start with no Wait and test and test and test, add delays and test some more.

Look at the input commands in the sample program that is included in the PEP download. Once you understand how the progress bar works, your program will be easy and no ProntoScript is required.
