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.
