Thank you for the tutorial! I don't mean to be greedy, but would you mind sharing your top MS Word typography tip that you think people should know? Aside from this one.
Turning on full justification and kerning do most of the heavy lifting.
The next biggest thing for most technical documents is maintaining the fidelity of drawings, diagrams, and charts. Many people paste low-resolution JPEGs into their documents, which looks like trash, especially on 4K screens or if printed.
Even older versions could paste in vector-format diagrams from other apps by using "Paste special -> Enhanced metafile".
Metafiles are the "native" vector format for the Windows GDI drawing and printing APIs, and provide the maximum quality and retain all of the original formatting details one-to-one. They're also small and efficient to display.
If none of those are possible, I insert images like company logos by scaling them up at the source to fill a 4K screen, take a screenshot, save as a PNG, and then insert that at a small size. This provides crisp edges at all but the most ludicrous resolutions.
