A tool dock at the bottom left holds exactly two tools: Select / move and T (Text). Plus Undo (⌘Z) and Clear all drawings (which asks first).
Pick T, click the canvas, type, press Enter. With a note selected, a contextual bar appears: font, size (−/+) and colour (a palette plus a custom picker). Notes can be moved and can be selected together with cards (rubber band or Shift-click) and then the whole mixed group drags as one.
On drawing. Four more tools exist in the data model (pen, arrow, rectangle, eraser) but they are removed from the palette and you cannot draw with them. Existing drawings still render and are not damaged; only authoring was removed.
⚠️ Also: publishing a board drops drawings entirely, while text notes do travel. See section 12.
