Microsoft Equation Editor 3.0. The piece of add-in for MS Word that has been there since 1995, and finally removed in 2018 due to a security problem. Yet, they are still everywhere for work related to high school maths. And there aren’t better replacements. I could type in the old equation editor blindfolded. Every keystroke has predictable behaviour. Ctrl-F for fractions, Ctrl-R for square roots. No other equation editors offered that. The new equation editor is not the same, I need to press so many unnecessary arrow keys just to get what I could have done before in half of the time.
