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.

Keyboard Layouts

Layout Name Overlay Key Top row keys (alone) Top row keys (with Overlay)
Chromebook / No overlay / F keys mapped to media keys None Media keys Media keys
Chromebook / Right alt overlay Right-Alt Function keys Media keys
Chromebook / Right alt overlay / F keys mapped to media keys
** default for GalliumOS 1.0 and later ** 		Right-Alt Media keys Function keys
Chromebook / Search overlay
previous default (1.0beta1), and Crouton default 		Super (Search) Function keys Media keys
Chromebook / Search overlay / F keys mapped to media key Super (Search) Media keys Function keys

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).
For instance, to remap the power key to Delete, add the following line in the appropriate file: key <POWR> {[ Delete ] };, and set the power button to "Do nothing" in the Power Manager menu.
