Show a specific line of a text-edit-document (content may changing) large on the screen

@JMichaelTX This is so cool! Thank you so much! I tested it out a bit and already got great suggestions I never thought of! The prompt from List action somehow wasn't on my mind at all. For this specific case it is not useful for me, but I have a bunch of other macros I wanna implement it in.
For my vocabulary-stuff I will check out your [FILE] Process Lines in Text File Macro. I will post my macro here than in the next days, when I have time for that! Thank you very much indeed!
