+## Obsidian Footnotes
+
+Great idea by [jacob.4ristotle](https://forum.obsidian.md/u/jacob.4ristotle/summary) posted in [Footnote Shortcut](https://forum.obsidian.md/t/footnote-shortcut/8872).
+
+> 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.
+
+That's what this does. 
+
+This plugin adds a new hot-key <kbd>Command</kbd>+<kbd>Shift</kbd>+<kbd>6</kbd> that when hit will insert a footnote with increased counter and move your cursor to the bottom of the file, add the other footnote pair and lets you type away...
+
+("6" because this is based on a US keyboard where the uptick character "^" is the shift-value of the same key. Customize hot-key as needed.)
+
+Let me know if you run into any issues!
+
+Cheers, 
+
+Alexis
