I have a huge set of packages with, arguably, far too many functions. Paring down the number of functions, while a good thing to do eventually, is something I just don't want to spend the time on right now. Rather I just want a way to turn off the symbols from showing up in the front-end by default.

I know this is possible as DeclareKnowSymbols doesn't show up or autocorrect until I have prepend System` to the name. And things like DataPaclets`GetDataPacletResource don't show up black despite the fact that they have values.

How can I set this up myself?
