Media keys and default keybindings

GalliumOS includes five keyboard layouts customized for Chromebooks. They can be configured from the GalliumOS/Whisker Menu, in Settings >> Keyboard >> Layout >> Keyboard Model.

Media keys and Function keys can be accessed either with or without pressing the "Overlay" key first, depending on your choice of keyboard layout.
