This is a fork from Benature's obsidian-underline plugin.
Simiarly to Benature's, simply use the hotkey cmd/ctrl+S to add an superscript format to the selected text, which will render <sup>content</sup> (or <sup></sup> when no selection). Additionally, the plugin will also undo the superscript when superscript text is selected.
cmd/ctrl+S is the default hotkey to save the open note. To remove this hotkey and avoid conflict, go to Settings (cmd/ctr+,), head to the Hotkeys section in the sidebar and find the hotkey for 'Save current file', and either delete the hotkey or add a custom alternative (I have ⌥+s).
