The nonstandard editing functionality in the original post is a bit buried, but it’s the ability to cut or copy an entire paragraph without selecting the text first that is specific to Obsidian. The OP mentions this in their 3rd bullet point:
“Whole wrapped line can be copied by Ctrl+C or cut out…by Ctrl+X when no text is selected.” [emphasis mine]
This feature is super-handy if you’re working with to do lists, as I’m doing in Obsidian (or if you’re a programmer, which is why I see this kind of functionality in programmer-leaning apps).
You can’t cut/copy unselected paragraphs by hotkey in a normal app in Windows. I double-checked right now!
