This hotkey lets you:
[^1]) with auto-incremented index in your text [^Citation]) in your text[^1]: or [^Citation]: ) at the bottom of your text 
After installing and activating this plugin, you still have to SET UP your hotkeys. This is easy and quick:
Settings -> Hotkeys -> Search for "Footnote" -> Customize Command -> Your preferred hotkeys
I personally use:

If you would like, you can further customize the plugin's behavior in Footnote Shortcut Settings.

Use case or problem:
I use Obsidian to take school notes, write essays and so on, and I find myself needing to add frequent footnotes. Currently, to add a new footnote, I need to:
- scroll to the bottom to check how many footnotes I already have
- type [^n] in the body of the note, where n is the next number
- move to the end of the note, type [^n] again, and then add my citation.
Proposed solution:
It would be convenient to have a shortcut to automate these steps. In particular, I envision that the shortcut would: Using the smallest natural number n that has not yet been used for a footnote
- add
[^n]at the insertion point- add
[^n]:to the end of the note, and move the insertion point there.
