What is the equivalent of double buffering in Mathematica called? I have looked that term up and nothing seems to shake out? The Mathematica book Index matches it to outputs but I am not finding the equivalent word in the Mathematica 5 book. I am trying to re-create workspaces found in other languages. Also Is there a way to cause "Hello World" to persist for a time and than fade? Other languages have a sync command, but I'm not sure how to perform this in Mathematica11.3? I'm working with Monkey 2, DarkBAsic, AGPKit and Python. Trying to recreate the effect in each of the Languages. Mathematica is older than some of these and their terminology for things existed prior to the rise of MS dominance so the Reserved words are different.
