minimizing latency

[OutrageProductions]

What @scook said is absolutely true.

While the PDF was last published in 2019 and covers  more than 95% of the current application (the Export dialog is a big update since then, for example), I still find it extremely useful for common things that I've forgotten about.

I also find it easier to auger into the PDF using search terms than local help. YMMV.
