Superscript and Subscript in the Card Editor

The card editor now supports superscript and subscript. Use it for things like footnote markers, chemical formulas, and French ordinals such as 1er and 2e.

This is for anyone who writes or edits cards, and it removes the need to hand-write <sup> tags in markdown blocks or work around the gap by copying text from another tool.

Apply the formatting from the toolbar, with Cmd/Ctrl + . for superscript and Cmd/Ctrl + , for subscript, or paste text that already has it from Word or Google Docs. There is no feature flag, no new permission, and no credit cost. Slack shows the text as plain text for now.

Try it first by selecting a character in any card and using the new toolbar buttons.
