The buttons at the bottom right open every panel and overlay, save the game and bring back the main menu.

With a keyboard attached to the iPad, the keys of the game view and the menu shortcuts work as on a Mac. Hold ⌘ to see the shortcuts.

Moving through panels with the keyboard

Turn on Keyboard navigation (Mac: System Settings ▸ Keyboard) or Full Keyboard Access (iPad: Settings ▸ Accessibility ▸ Keyboards). Then Tab moves from button to button in the panels and menus, a blue ring shows where you are, and Space presses the button. Esc closes the panel at the bottom, one per press.
