Excalidraw shapes

Shape keys are built in; nothing to configure.

1. In a blank Excalidraw board, add a text element and type login api. Select the words.
2. Hold ⌘⌥, type 2ra, release.
3. The words become [login] → [api]: two boxes and an arrow, all editable Excalidraw shapes. Move them, restyle them, or press ⌘Z to get the words back.
