Guessing what they mean by show codes on cursor. Showing markdown around the cursor is now in Obsidian, but previously it was in Typora, FoldingText, and a circa 2016 web app called "usecanvas":

https://github.com/usecanvas

There may be examples prior to that, but that's the earliest that I recall.

I'm not sure what is meant by local modal editing - is that describing what logseq does? It switches a block to plain markdown when you're editing it.

I thought word perfect show codes was in another pane, but it's been a very long time since I've seen it, and I didn't use it personally.
