The Figma project includes a Bottom Bar component with File-level actions (such as undo, redo, indent, comment, etc.)
These actions are currently achievable through keyboard shortcuts, so gathering the method names from the handleGlobalKeydown method is a good way to go.

Below are the current proposals for the bottom bar (and IDE action buttons). New ones are welcome ✨, but validating usability through user tests is required to define should will be implemented.
