Alright here is my work:
1. Open up Sign Text editor
2. Open up 2nd browser tab
3. Go into Sign Puddle dictionary
4. Copy sign into another Sign Text document (not work)
5. Will copy in Apple Page document.
6. My purpose is when I find a mistake I would like to go to the dictionary, find the correct sign or similar sign, bring it into SignText for further editing without needing to write the whole sign over. ???
