View source for 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.

These layouts are stored in /usr/share/X11/xkb/symbols/chromebook* . To modify the functionality of a key, one can make changes to the appropriate file (as root).<br>
For instance, to remap the power key to Delete, add the following line in the appropriate file: <code>key <POWR> {[ Delete ]       };</code>, and set the power button to "Do nothing" in the Power Manager menu.
