Setup gathers keyboard settings under one submenu
Setup gathers Keybindings, the layout picker and Input Methods under one Keyboard submenu. A change merged into quattro replaces Setup > Typing and the top-level Keybindings row. Setup > Input stays where it was.
The layout picker is Keyboard Inputs, formerly Keyboard Layouts. The manual and the input-methods page point at the new paths, and translations follow through the sync workflow.
