[KM8] Find and Replace Text in Actions

@gglick, and all:

:exclamation: You should be aware of two issues:

  1. Changing ALL text in the XML string could be dangerous, and result in an unusable macro, since you might inadvertently change some key strings in the XML.
  • So, I personally would not try to change any text other than that which I am very sure is unique text created by me, like an obviously unique variable name like "CMC__FootNoteNumber".
    .
  1. This will change only those parts of Actions that are plain text.
  • It will not change rich text areas, like in Comments and Display Window.
  • I have documented this here.
