I don't have the expertise or the patience to describe details of the basic operation of ProntoEdit. (I don't have a Pronto myself, and I only use or edit the IR signals in CCF files, not the graphics).

Maybe some other expert will see your questions above. But it is buried in a thread whose title may stop the people who might answer basic ProntoEdit questions from even reading this far.

You might want to start another thread for basic ProntoEdit questions or you might want to try the help built into ProntoEdit.
