Editing text: words, font, size and colour

Double-click a text box to type in it (on a phone: tap it, then Edit).
With it selected, the toolbar above the page changes font, size, colour, bold, alignment, spacing and lists. On a phone the bar at the bottom shows Font, Size and Colour: each opens a short panel and the design stays in view.
To make text bigger or smaller, use Size; the box grows with the words.
Smart write (on the same toolbar) rewrites, shortens, changes the tone or translates it.
