I’m not sure if this is possible, but: I would love a keyboard shortcut for inserting a footnote (really, a plugin enabling such a thing). Since adding a footnote in Markdown takes many, many keystrokes, it’s cumbersome enough that I avoid doing it although I would otherwise do it often.

There was a similar thread recently about it, check here: https://forum.obsidian.md/t/footnote-hotkey/13022/4?u=maned
