Double clicking selects a word, and triple-clicking selects the whole line. If I double- or triple-click-and-hold, I can drag the mouse to expand the selection word-wise or line-wise, not just character-wise. This works with the paragraphs of text in the body of this blog post, too.
I had no idea that you could end with a drag to expand your selection by word or by line like that. That's really cool. (The author's using Linux, but it works on macOS too.)
This thread just makes me think of the thankless job of native frontend developers working on Linux/macOS/Windows OSes that made these nuances and behaviors work exactly to a specific standard. Ok, maybe not thankless in the case of Mac and Windows since they probably got paid. :) But yeah, I imagine all the edge cases aren't easy to handle.
